Uninvited Belly

I have been taking zoloft for about 5 months. I was so edgey, paranoid, and suidicidal before I went on it.  Now I feel like a totally person and I even enjoy talking to strangers, which I could barely do before.  Recently, my girlfriend diagnosed me with dun-lap disease.  My belly done lapped over my belt (literally).  I have always been really skinny, so even now, I don't mind it too much.  I don't want to get much bigger though. 

Also, does anyone know if drinking alcohol has any serious side-effects with zoloft?  My doctor says it doesn't, but I know he's flat out lying to me.  I've seen it on the label of the bottle!!!  However, is it a small concern, or small enough for him and other doctors to say it isn't a big problem?  Thanks for any information.  Best of luck to all of you guys.
