LPT: When You’re Done Drinking Alcohol for the Night, Start Drinking Lots of Water

Anyone who has ever woken up with a pounding headache, dry mouth, and deep regret knows the pain of a hangover. The original Life Pro Tip sounds simple, almost painfully obvious but the reason it keeps resurfacing is because it works.

Drinking water after alcohol doesn’t magically erase consequences, but it can significantly reduce how rough the next morning feels.

That said, Reddit users were quick to point out that the advice is both incomplete and often misunderstood. So what’s actually happening in your body when you drink alcohol, and how much can water really help?

Let’s break it down.

Why Alcohol Makes You Feel Terrible the Next Day

Alcohol is a diuretic, meaning it increases urine production. According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), alcohol suppresses vasopressin, a hormone that helps your body retain water.

When vasopressin levels drop, your kidneys send more water straight to your bladder instead of reabsorbing it.

That’s why:

• You pee more while drinking

• You wake up dehydrated

• You experience headaches, dizziness, dry mouth, and fatigue

A study published in Alcohol Research: Current Reviews notes that dehydration is a major contributor to hangover symptoms, particularly headaches and nausea. While dehydration isn’t the only cause of hangovers, it’s one of the most preventable ones.

The “Toxins” Myth (And What Water Actually Does)

Several commenters correctly pushed back on the idea that water “flushes toxins.” That wording gets thrown around a lot, but medically speaking, it’s misleading.

Your liver is responsible for metabolizing alcohol into acetaldehyde and then into acetate, which your body can eliminate. Water doesn’t neutralize alcohol or remove toxins directly.

What water does do:

• Restores fluid balance

• Supports kidney function

• Helps regulate blood pressure

• Reduces the severity of dehydration-related symptoms

Dr. Aaron White, a senior scientific advisor at the NIAAA, explains that hydration helps your body function more efficiently during recovery, even though it doesn’t speed up alcohol metabolism itself.

In short: water won’t sober you up, but it can make recovery far less miserable.

Timing Matters: Don’t Wait Until the End

One of the most upvoted Reddit responses nailed the real pro tip: don’t wait until you’re done drinking.

Health professionals often recommend the “one-for-one” rule:

• One alcoholic drink

• One glass of water

This approach slows alcohol intake, maintains hydration, and reduces overall consumption—three wins in one habit.

A 2016 study in Appetite found that people who drank water between alcoholic drinks consumed significantly less alcohol overall, without reporting reduced enjoyment.

Electrolytes: Why Water Alone Isn’t Always Enough

Alcohol doesn’t just dehydrate you, it also affects electrolyte balance, including sodium and potassium levels. That’s why some people swear by sports drinks or oral rehydration solutions.

According to Cleveland Clinic dietitians:

• Water is essential

• Electrolytes can help if you’ve been drinking heavily

• Sugary drinks should be used in moderation

Options like low-sugar electrolyte drinks or diluted sports drinks can be more effective than plain water for severe dehydration.

Other Small Habits That Make a Big Difference

Several Reddit commenters added tips that sound minor but are surprisingly impactful:

1. Eat Before and After Drinking

Food slows alcohol absorption. High-protein and healthy-fat foods are especially helpful.

2. Brush Your Teeth (Carefully)

Alcohol is acidic and promotes bacterial growth. Dentists recommend waiting 30–60 minutes before brushing to avoid damaging softened enamel, rinse with water first.

3. Sleep Position Matters

Alcohol disrupts REM sleep and worsens acid reflux. Sleeping slightly elevated can reduce nausea and discomfort.

The Age Factor Is Real

One comment jokingly warned younger drinkers that hangovers are “coming for them.” Unfortunately, science backs that up.

As we age:

• Metabolism slows

• Muscle mass decreases (less water storage)

• Liver efficiency declines

A study in BMJ Open found that older adults report more severe hangover symptoms even with similar alcohol intake, largely due to reduced hydration reserves.

So yes—habits you build now will matter later.

What This LPT Gets Right (And Wrong)

Right:

• Hydration helps reduce hangover severity

• Drinking water after alcohol is beneficial

• Consistency matters

Wrong or Oversimplified:

• Water does not “flush toxins”

• Waiting until the end isn’t ideal

• Water alone won’t prevent all hangovers

As one Reddit user bluntly put it: “This feels more like a life amateur tip.” And honestly? That’s fair—but amateur tips are often the ones people actually follow.

Check out how the community responded:

Some users backed it with actual science, others roasted it for being painfully obvious, and a few proudly admitted that drunk them has never once listened to sober logic. 

From hydration experts to professional bad-decision-makers, the comment section quickly turned into a mix of genuine advice, sarcasm, and the kind of brutal honesty only the internet can deliver.

The Takeaway

Drinking water after alcohol won’t undo a long night, but it can absolutely make the morning survivable. The real lesson isn’t just drink water later, it’s hydrate throughout, eat properly, and know your limits.

Or, as Reddit summarized it best: drunk you may not be responsible but sober you can plan ahead.
