It starts as a localized rebellion in your gut. First, it’s just the standard "I shouldn't have had that last tequila shot" nausea, but then it transforms. You’re hovering over the toilet for the fifth time in an hour, ribs aching, throat burning, and wondering why your body has decided to set itself on permanent eject mode. If you can't stop throwing up after drinking, you aren’t just "hungover." You’ve likely crossed the line into a physiological emergency that doctors often call gastritis or, in more severe cases, alcohol poisoning.
It's miserable. Honestly, it's one of the most draining physical experiences you can have without being "sick" in the traditional sense. Most people think they just need to "wait it out," but when the vomiting becomes cyclical, your body is essentially trapped in a feedback loop of irritation and dehydration.
The Science of Why Your Stomach Is Hating You
Alcohol is a gastric irritant. That’s the simplest way to put it. When you consume ethanol, your stomach lining produces more acid than usual. This leads to inflammation, known as acute gastritis. According to the Mayo Clinic, this irritation can cause gnawing or burning aching (indigestion) in your upper abdomen that may become either worse or better with eating. But when you’ve had too much, the "worse" part wins.
The vomiting is a defense mechanism. Your brain’s area postrema—the vomiting center—detects toxins in the blood and sounds the alarm. But even after the alcohol is physically gone from your stomach, you might keep retching. Why? Because the lining of your stomach is so raw and inflamed that even a sip of water feels like a direct attack.
Then there's the acetaldehyde. When your liver breaks down alcohol, it creates this byproduct, which is actually more toxic than the alcohol itself. If you drank faster than your liver could process, that acetaldehyde builds up, making you feel like absolute death.
When "Normal" Puking Becomes Dangerous
There is a massive difference between throwing up once and feeling better versus being stuck in a loop. If you can't stop throwing up after drinking, you might be entering the territory of Mallory-Weiss tears. These are small tears in the tissue of your lower esophagus caused by the sheer force of violent coughing or vomiting. If you see bright red blood in your vomit, that is a clear sign that you need to stop reading this and go to an Urgent Care or ER.
Dehydration isn't just "feeling thirsty." It’s an electrolyte imbalance that can lead to heart palpitations and seizures. You're losing potassium, sodium, and magnesium every time you heave.
Dr. Robert Glatter, an emergency physician at Lenox Hill Hospital, often points out that the real danger of persistent vomiting isn't just the discomfort; it’s the metabolic chaos happening inside. Your blood pH can actually shift, leading to a condition called metabolic alkalosis because you're losing so much stomach acid.

Why Water Might Be Making It Worse
This is the part that trips everyone up. You feel dehydrated, so you chug a giant glass of water. Two minutes later, it’s back in the toilet.
Your stomach is currently a "no-fly zone." Throwing 8 ounces of liquid into an inflamed, spasming organ is like trying to put out a grease fire with a bucket of water—it just splashes back at you. You have to be sneakier.
Instead of drinking, you should be micro-dosing fluids. We’re talking a single teaspoon of room-temperature Gatorade or Pedialyte every five to ten minutes. If that stays down for an hour, you move up to two teaspoons. It’s tedious. It’s annoying. But it’s the only way to rehydrate without triggering the gag reflex.
The Mystery of the "Second Day" Vomit
Sometimes, you don't even start throwing up until the next morning when the alcohol is technically out of your system. This is often due to Alcohol-Induced Ketoacidosis. This usually happens to people who haven't eaten much while drinking. Your body runs out of glycogen, starts burning fat for fuel, and produces ketones. This turns your blood acidic, which—you guessed it—makes you vomit uncontrollably.
If your breath smells fruity or like nail polish remover and you can't stop retching, your body is literally starving for glucose, but your stomach is too irritated to take it. It’s a vicious cycle that often requires an IV drip of saline and dextrose to break.
Myths That Are Actually Killing You
- Coffee: Please, stop. Caffeine is a diuretic and a gastric stimulant. It’s literally the worst thing you can give an inflamed stomach.
- Hair of the Dog: Drinking more alcohol to stop the hangover is like trying to put out a fire with gasoline. It might numb the receptors for an hour, but the rebound effect will be twice as violent.
- Forcing yourself to eat: If you are still in the active "heaving" phase, food is your enemy. Your digestive system has effectively shut down to focus on "damage control."
How to Actually Stop the Cycle
If you’re currently in the thick of it, there are a few evidence-based steps to take.
First, stop all intake for at least one hour. No water, no crackers, nothing. Let the stomach muscles stop spasming.

Second, try a B6 supplement if you can keep a tiny pill down, or better yet, ginger. Real ginger—not the sugary soda that contains 0% actual ginger. Ginger contains gingerols and shogaols that help speed up gastric emptying and calm the "vomit center" in the brain.
Third, monitor your temperature. A fever after a night of drinking can indicate pancreatitis—inflammation of the pancreas—which is a serious medical emergency often triggered by heavy alcohol consumption.
The Role of Congeners
Not all alcohol is created equal. If you find that you can't stop throwing up after drinking red wine or bourbon specifically, but you're okay with vodka, it’s likely the congeners. These are impurities produced during fermentation. Darker liquors have more of them. Your body sees these as foreign invaders and works overtime to get rid of them. Switching to "cleaner" spirits might help in the future, but right now, your priority is just survival.
When to Call for Professional Help
Don't be a hero. Alcohol poisoning is a leading cause of preventable death. If you or someone you're with shows these signs, call for medical help:
- Confusion or "stupor" where they can't be fully woken up.
- Blue-tinged or pale skin.
- Slow breathing (less than eight breaths per minute).
- Seizures.
- Continuous vomiting that lasts more than 12 hours without any retention of fluids.
In a hospital setting, they can give you Zofran (Ondansetron). This stuff is a miracle. It blocks the signals in your nervous system that trigger nausea. They’ll also pump you full of fluids and electrolytes, which will make you feel human again in about 45 minutes.
Actionable Next Steps for Recovery
If you are currently stable but still feeling like a shell of a person, here is the protocol to follow to get back on your feet:
1. The 60-Minute Reset
Do not put anything in your mouth for 60 full minutes. This includes ice chips. Sit upright; laying flat can allow stomach acid to creep into your esophagus, triggering more nausea.

2. The Teaspoon Rule
Once the hour is up, take one teaspoon of a 50/50 mix of water and an electrolyte drink (like Pedialyte). Wait 10 minutes. If it stays down, repeat. Do this for two hours before trying to take actual sips.
3. The Temperature Check
Use room temperature or lukewarm liquids. Cold liquids can cause the stomach to cramp, which often leads to another round of vomiting.
4. The BRAT Transition
Only once you have successfully held down water for 4+ hours should you try the BRAT diet: Bananas, Rice, Applesauce, and Toast. These are low-fiber, bland foods that won't overwork your digestive tract.
5. Replenish Vitamin B1 (Thiamine)
Alcohol severely depletes Thiamine. This depletion is what causes that "brain fog" and shaky feeling the next day. Once you can eat, focus on foods like beans, seeds, or a B-complex supplement to help your nervous system recover.
6. Assess the "Why"
If this happens every time you drink, even in small amounts, you may have developed an alcohol intolerance or an allergy to specific ingredients (like sulfites in wine or grain proteins in beer). Keep a log of what you drank to see if there's a pattern, as your body might be trying to tell you it lacks the specific enzymes to process certain toxins.
7. Get Sleep, but Stay Propped Up
Sleep is the best healer, but do not sleep flat on your back if you are still feeling nauseous. Use a few pillows to keep your head elevated to prevent aspiration (choking on vomit in your sleep), which is a major risk after heavy drinking.
