urinary tract infection
"Prescribed generic Bactrim DS, 2x/day for 3 days. Just took my last dose and minimal side effects. I always ate a big substantial meal before taking this medication even though I had loss of appetite (ate food that had tons of starch). Also, drank tons of water after and throughout the day. I was constantly peeing but at least I knew I was drinking enough. Had minor upset stomach and fatigue but still very functional esp when the pain from UTI was gone. Took a day and half to feel relief."
