Stomach Pains and Vomiting After a Night of Drinking

Hello,

I am a 21 year old male. I started drinking socially a few years ago and I have never had a problem with vomiting or stomach pains unless I drank too much.

About five weeks ago, I had a late night, consuming quite a lot of drinks. The next day I was vomiting all day. This was the first time I had ever vomited the day after drinking. Then, about two weeks later, I had a good amount of drinks and the next day I was vomiting even more. I was vomiting clear and yellowish/green liquid.

Now, whenever I drink, the next day my stomach is in excruciating pain. When I drink a lot, I always vomit.

Has anyone experience anything like this or knows what is going on? Any input would be greatly appreciated.

Thank you.

Nick
