Hangover Cures: What Actually Works and What's a Myth

You wake up on a Saturday morning and immediately know - last night was "a bit" too much. A hammer in the head, mouth as dry as a desert, stomach doing somersaults, and the thought of food makes you nauseous. Classic hangover. And then the desperate googling begins: "hangover cure", "how to get rid of a hangover fast", "best remedy for a hangover".

The internet floods you with thousands of tips. Grandma said something about pickle juice, a friend swears by a cold beer in the morning, an influencer praises a detox shake costing €8. Who's right? What actually works?

Today we'll break it all down - as a pharmacist I'll show you what science says about hangover symptoms, which methods make sense, and which are pure myths. Because you deserve the truth, especially when your head is about to explode.

What Is a Hangover and Why Does It Wreck You?

Before we get to medications and tricks, let's understand what's actually happening in your body after alcohol.

A hangover (scientifically: veisalgia) isn't one thing. It's a whole bouquet of unpleasant symptoms resulting from alcohol poisoning and its metabolites. Here's what happens:

1. Dehydration - The Main Culprit

Alcohol is a diuretic - it tells the kidneys to excrete more water than you drink. Result? You lose up to 3-4 times more fluid than normal. You also lose electrolytes (sodium, potassium, magnesium).

Effect: Headache, dry mouth, dizziness, fatigue.

2. Acetaldehyde - Poison in Your Body

When the liver breaks down alcohol, it produces acetaldehyde - a compound 10-30 times more toxic than alcohol itself. This is what's responsible for most hangover suffering.

Effect: Nausea, vomiting, headaches, trembling hands, sweating.

3. Digestive System Disruption

Alcohol irritates the stomach lining, increases stomach acid production, and slows stomach emptying.

Effect: Nausea, vomiting, abdominal pain, diarrhoea.

4. Blood Sugar Drop

Alcohol blocks glucose production in the liver. Less glucose = less energy for the brain.

Effect: Fatigue, irritability, difficulty concentrating, trembling.

5. Sleep Disruption

While alcohol helps you fall asleep, it destroys sleep quality - especially the REM phase (deep sleep). You wake up tired, even if you slept 8 hours.

Effect: Feeling permanently tired, brain fog, irritability.

6. Inflammatory Response

Alcohol activates the immune system, causing inflammation throughout the body.

Effect: General malaise, muscle aches, memory problems.

As you can see, a hangover isn't one thing to cure. It's a full spectrum of physiological problems. And that's why there's no single "magic pill" for a hangover.

What Actually Works - Science-Backed Methods

OK, let's get to the point. What can you do to feel better?

1. Rehydration - Priority Number One

This is the most obvious and most effective advice. Full stop.

What to drink:

• Water - large amounts, in small sips throughout the day
• Isotonic drinks - replenish electrolytes (sodium, potassium)
• Coconut water - a natural electrolyte, gentler on the stomach
• Broth - yes, seriously! Salt + fluids + easy to digest

How much to drink? Minimum 2-3 litres of water throughout the day after a hangover night. If your urine is dark - you're not drinking enough.

Tip: Best to start rehydrating before bed - drink 2 large glasses of water before lying down. This reduces the suffering in the morning.

2. Electrolytes - Not Just for Athletes

You lose not only water but also minerals. Replenish them.

Options:

• Electrolyte powders - available at pharmacies (look for ones without artificial colouring and with low sugar content)
• Isotonic drinks - but watch the sugar (may worsen nausea)
• Oral rehydration solution - the medical standard (available at pharmacies, cheap and effective)

Practical tip: Keep a supply of electrolyte powders at home. Check prices on CheaperForDrug - you can save 30-40% compared to branded isotonic drinks.

3. Food - But the Right Kind

You probably don't have an appetite, but eating will genuinely help.

What to eat:

• Eggs - contain cysteine, an amino acid that helps break down acetaldehyde
• Bananas - rich in potassium, which you've lost
• Avocado - potassium + healthy fats
• Toast with butter - carbohydrates will raise blood sugar
• Porridge - gentle on the stomach, provides energy
• Soups - rehydrating and easy to digest

What to avoid:

• Greasy fast food (will overload the stomach)
• Spicy food (will irritate the lining)
• Coffee on an empty stomach (will increase stomach acid production)

4. Painkillers - But Not Just Any

Headache? You can take a tablet, but carefully.

Safe options:

• Ibuprofen - effective for headache, but may irritate the stomach (take after eating!)
• Paracetamol - but only if you didn't drink heavily and your liver is healthy

NEVER take:

• Large doses of paracetamol - alcohol + paracetamol = deadly dangerous for the liver
• Aspirin on an empty stomach - combined with alcohol it increases the risk of stomach bleeding

Safe paracetamol dose: Maximum 500-1000 mg (1-2 tablets), no more than 3000 mg in 24 hours after a hangover night. If you drank really heavily - skip paracetamol entirely.

5. Time and Rest

This is the most scientific truth: the only certain cure for a hangover is time. Your body needs to eliminate alcohol and its metabolites. This takes 12-24 hours.

What you can do:

• Sleep as much as you can (sleep supports recovery)
• Avoid physical exertion (you'd dehydrate yourself further)
• Stay home, limit stressful activities

6. Vitamins and Minerals (Optional)

Some studies suggest they may help:

B-complex vitamins - alcohol depletes B vitamin stores. Supplementation may speed recovery.

Magnesium - often lost with alcohol, and its deficiency causes fatigue and headaches.

Zinc - supports alcohol metabolism.

Are they miraculous? No. Might they help a bit? Perhaps. But the priority is water, electrolytes, food, and time.

Popular Hangover Myths

Time to bust a few popular superstitions.

Myth 1: "Hair of the dog - drink a beer in the morning"

Truth: This is the worst idea. Yes, you might feel momentary relief (alcohol temporarily masks symptoms), but you're actually just prolonging the suffering. You're giving your body more toxins to process. Result? The hangover will return, only worse.

Verdict: Don't do this. Ever.

Myth 2: "A greasy meal before drinking will prevent a hangover"

Truth: Eating before drinking does genuinely slow alcohol absorption - you'll feel the effect later and less intensely. But it won't prevent a hangover if you drink too much. It just delays the problem.

Verdict: Eat before drinking (that's good), but it's not a "licence to drink without consequences".

Myth 3: "Lemon water detoxifies"

Truth: Water helps (it hydrates), but lemon has no magical detoxifying properties. Your liver handles detoxification, not lemon.

Verdict: Drink water. With lemon, without lemon - doesn't matter. But don't think the lemon does anything special.

Myth 4: "Coffee will sober you up and help with the hangover"

Truth: Coffee does NOT sober you up. Caffeine may relieve headache in some people, but it also dehydrates and irritates the stomach. If you drink coffee - hydrate well first.

Verdict: Coffee isn't bad, but it's not a miraculous cure. Water is more important.

Myth 5: "Pickle juice for a hangover"

Truth: Pickle brine does indeed contain salt and electrolytes. It may help a little with rehydration. But it has no special power - broth, isotonic drinks, or water with salt work similarly.

Verdict: If you like it - drink it. Won't hurt. But it's not better than other electrolyte sources.

Myth 6: "Hangover pills from advertisements work miracles"

Truth: Most "hangover cures" are blends of vitamins, electrolytes, herbs, and sometimes painkillers. They may help a bit (mainly thanks to vitamins and electrolytes), but they don't work miracles. Often you're overpaying for marketing.

Verdict: They may help, but you can build your own kit cheaper: water, electrolytes, B vitamins, ibuprofen.

How to Prevent a Hangover - Better Safe Than Sorry

Now that we know how to treat a hangover, let's talk about prevention. Because the best hangover is the one you don't have.

1. Drink Less - Obvious but True

More alcohol = worse hangover. There's no escaping this. If you want to avoid a hangover - simply drink less.

Safe limits (if you want to avoid a hangover):

• Women: 1-2 drinks
• Men: 2-3 drinks

One drink = 350 ml beer (5%), 150 ml wine (12%), 45 ml spirits (40%).

2. Alternate Alcohol with Water

The golden rule: after every alcoholic drink, have a glass of water. This slows your pace and hydrates simultaneously.

3. Eat Before and During Drinking

A full stomach slows alcohol absorption. Eat something before going out and snack during.

4. Choose Wisely - Light Spirits Are Better Than Dark

Dark alcoholic drinks (whisky, brandy, rum, red wine) contain more congeners - substances produced during fermentation that worsen hangovers. Light spirits (vodka, gin, white wine) have fewer.

Ranking from least to worst hangover:

1. Vodka (neat)
2. Gin
3. White wine
4. Beer
5. Red wine
6. Whisky/rum/brandy

5. Avoid Mixing Drinks

Beer + vodka + wine = recipe for disaster. Stick to one type of alcohol for the entire evening.

6. Before Bed: Water + Food + Electrolytes

Before you fall asleep:

• Drink 2 large glasses of water
• Eat something light (toast, banana)
• Take an electrolyte supplement or drink an isotonic drink
• Leave water by the bed

This genuinely reduces the morning suffering.

When to See a Doctor

Most hangovers are unpleasant but harmless. They'll pass within 24 hours. But there are situations when you need to act:

Go to a doctor or A&E if:

• You're vomiting blood or have tarry black stools (could be stomach bleeding)
• You have severe, persistent abdominal pain
• You're disoriented, hallucinating, or having seizures
• You're breathing very slowly (below 8 breaths per minute)
• You have cyanosis (bluish skin, lips)
• You can't wake up or are difficult to rouse

These could be symptoms of alcohol poisoning - a life-threatening condition. Don't wait - call emergency services.

Compare Prices on Hangover Products

What's worth keeping at home:

• Electrolyte powders/tablets

In total you can spend €5-8 and have a kit for several hangover mornings. Or overpay €20 for a "premium" hangover product from an advertisement. The choice is yours.

Summary - What Actually Works?

Water and electrolytes - absolute priority. Drink plenty and regularly.

Food - eggs, bananas, porridge, toast. Avoid greasy fast food.

Rest and sleep - give your body time to recover.

Painkillers - ibuprofen after eating. Paracetamol only in small doses and if you didn't drink heavily.

Time - the only certain cure. A hangover will pass in 12-24 hours.

DO NOT drink alcohol in the morning - it only prolongs the suffering.

DO NOT take large doses of paracetamol - dangerous for the liver after alcohol.

DO NOT believe in magical detoxes - your liver handles detox, not lemon in water.

Excessive alcohol consumption is harmful to health. If you have a problem with alcohol, consult a specialist.

Remember: The best hangover cure is not having one. Drink responsibly, know your limits, alternate alcohol with water, and eat before drinking. And if you do overdo it - hydrate, eat, rest, and give your body time.

And for next time? Maybe think twice before that fifth drink. Your head (and stomach) will be grateful.
