Amoxicillin / clavulanate
"Started taking the medication 7 days prior to surgery and continued for a total of 14 days. Stomach issues began right away but not excessive. Got worse. Stomach cramps (not abdominal), dizziness, sweats, nausea, extreme fatigue. Did it work? No idea, this was a preventative measure and since I was having a procedure that I do NOT want to repeat, I stuck with it. Now it's 48 hours after the last dose and now I have the abdominal cramps and diarrhea. Hoping this doesn't last too long. I will not take this drug ever again. I've lost 15 days of my life so far. I've been through cancer treatment and sometimes the cure is worse than the disease"
