Poisoning. You have alcohol poisoning.

I feel like no one is addressing the fact that this shouldn't be happening very frequently as your making it sound. Either you're drinking too much, to the point of being alcoholic. That or something is wrong with your body.

Because alcohol is poison and you’re drinking too much of it. If you’re puking at all you already over did it.

Skill issue

your body has quit trusting your judgement of what you put in.

Your body won’t let you throw up more than you can in one go. If you haven’t noticed, when you throw up, your whole body tenses, you’re wrenching hard, and you can’t breathe. If you’ve been drinking for hours, you have a lot of poison in you. If it takes multiple purges, your body couldn’t get it out in one go. You’re expelling air as well as everything in your stomach. So you’re starving for air, expending a lot of energy, and your airway is full of vomit. Your body knows you need to breathe, so it won’t just expel everything no matter how long it would take. Not to mention your muscles are only so strong, and those muscles don’t get worked out super regularly.

So basically your body just can’t. If you’re puking more than once, you needed to. Because there have been plenty of times where I’ve eaten something off and I threw up once and felt better/didn’t need to throw up again.

But also, I agree with everyone else. It sounds like you have a problem.

Because the toxins your body is reacting to are already in your bloodstream. It'll take time for those to get metabolized by your liver, and how much or little you vomit won't change how much work your liver has to do.

I mean when you say you've been drinking, how much?

No you shouldn't be puking if you're drinking unless you're drinking way too much

And it's not good. Puking is bad.

Your stomach ain't ready for it yet. Vomiting forces the usual flow of what you've taken in to flow to the reverse direction and dragging things, like the acids in your stomach, with it.

It's quite a shock for the body. Depending on the severity of the vomiting, it can take a little, until it's ready to 'take in' again.

IANAD this is just what i experienced myself with vomiting in the past and what my brain made out of it.

Take a bag, fill it with water, and grip it loosely at the top so all your fingers wrap around like a loose fist.

Now, without turning the bag, use your other hand to empty it by squeezing out the water.

You get most of it out, but there's still some in there, even if you squeeze violently and it seems like nothing else can come out.

Also, for most of human history, if you've poisoned yourself ingesting something, chances are the next thing you're ingesting is still poisoned. It's only recently we've worked out distilled poison and purified water. So, biologically speaking, better to just be sick for a day so you can get to a different water/food source.

Do you also get flushed in the face? Seems like some kind of alcohol intolerance. Theres a gene thats common in east asians that can cause this. A vietnamese friend of mine has a similar reaction when he drinks.

It may be a medical issue. Maybe you are histamine intolerant, or allergic/intolerant to some other ingredient of the stuff you're drinking?

Vomiting can be a symptom of dehydration. You couple the body's toxin response from the booze with the dehydration caused by the booze, and this can lead to vomiting. In fact, most classic hangover symptoms are dehydration symptoms.

The first place your body starts to absorb alcohol is through your mouth, especially under your tongue. You, of course, absorb alcohol through your stomach as well. The highest rate of alcohol absorption happens in the small intestines, however. This is why your blood alcohol level continues to go up well after your last drink.

Our bodies can process, on average, one serving of alcohol per hour. The serving size depends on the alcohol by volume of the specific drink, the person's biological sex, and the person's weight. If you drink more than your body can process, it begins to build up in your blood stream and cause intoxication. Once it is in your blood stream you are at your body's mercy to process it. There is no real, effective trick to "sober up". Tactics may make you feel more alert, but your BAC won't change. Food won't help, coffee won't help, and slamming water won't help speed this process up.

Basically, unless you've chugged a bunch of alcohol in a very short amount of time, vomiting won't save you. By the time you feel nauseous, the damage is already done. Your body has absorbed and is processing the alcohol you already drank.

I have an interesting question regarding this. I drink occasionally but not to the point where I'm shitfaced, usually not feeling very drunk or not drunk at all and yet I still throw up.

I throw up multiple times a couple of times in a row and I have no idea why this happens. I wouldn't believe it's alcohol poisoning since it has happened at as low as 3 beers (regular strength, not any ridiculous IPA type beers).

I'm curious if any more educated people have any idea what this can be about. I've been trying to figure this shit out for years but have just mostly given up on drinking instead.

You can puke if your stomach is full
