Why did i throw up from one shot?

So I am a huge alcoholic.. But last night for some reason I barely had one shot and I puked ... I don't know why my body jsut rejected it!! I dont understand what happened.. Some people say its because im pregnant.. But I highly doubt it

well if your pregnant you shouldnt drink, and if you dont know if your pregnant, take a test

Wow.
You really shouldn't be drinking if you're pregnant.

if your an alcoholic you should get some professional help and you definitely shouldn't be drinking if your pregnant

that sometimes happens if your body is just a little overloaded from alcohol and needs a break... just give it a rest for a bit, let it get rid of the toxins...

and uh yeah, take a pregnancy test if you suspect pregnancy...

I never said I was pregnant I was just saying

lol, ok, well it happens to the best of us (the mild alcohol poisoning or whatever it is). I remember once the smell of vodka made me want to puke. Lay off for a bit. And start off with mixed drinks next time...
