Hey guys, Recently when ever I drink alcohol I tend to either vomit, get diarrhea or have extremely bad gas. 

I generally drink 3 days a week:

Tuesday: 1-2 Drinks

Thursday: 1-2 Drinks (Once every few months ill have 3-4)

Saturday: 12ishDrinks

Probably 2 weeks ago. I started getting bad reactions to alcohol. After drinking roughly half a carton I ended up with I guess a very mild diarrhea. Which lasted for about 30-50 minutes. The following week with about the same amount of drinks I had to have one solid go at vomiting.  So right now I have very bad gas from drinking 3 drinks. 345ml 5% alcohol. I had to poop once which was pretty sloppy.

Those are a few examples. I've vomited off 2 drinks as another eg. 

I never mix drinks and I have tried changing sorts of alcohol (cider/bourbon) yet it still continues to happen. 

Looking for any advice as New years is coming up and she's gonna be a big one. I want it to be the normal fun with no literal sh*t attracted. 

Thanks in advance
