Antibiotics made band tighter?

I was prescribed levaquin for a breast infection. I noticed a few hours later, my water was going down slowly as if I'd just had a fill. Well, due to some other bad side effects my doc changed me to clyndamycin. I was just wondering if anyone else had problems with antibiotics. I just started the new one today. It has side effects of nausea, light diarreah, and vomiting. Of course, I am praying I dont vomit. I just hate that this medicine has to come with all these horrible side effects.
