I Drank Too Much Alcohol On New Years Eve And

I drank too much alcohol on New Years Eve and might have gotten mild alcohol poisoning. I was sick for about 3 days. I've tried to drink since then and it just leads to me drinking a tiny bit and feeling like I'm going to puke and just overall crappy but not drunk and I stop before I end up puking. I also have lost my appetite. About 3 times I have been eating supper and it just makes me feel sick to my stomach. I eat probably about half of what I did before. What do you think could be wrong?
