urinary tract infection
"This is day 2 taking this med. It makes me very queasy and very tired. The nausea and tiredness start about 30 minutes after I take one, and seem to last for 6 or 7 hours. I try to take it with food, but I don't have much appetite  (not gonna be mad about that tho). The uti seems pretty much gone, but I'm also taking Azo."
