bronchitis
"After just 2 doses of planned 10 day 2x/day 875mg treatment got VIOLENTLY ILL, literally projectile vomited on brand new carpet as I couldn't get the 10 feet to toilet fast enough.  Stopped medicine immediately but still had massive, continuous diarrhea for almost 3 weeks, lost 17 lbs in 14 days! It was so bad/went on so long the Dr actually tested me for Cdiff, which was negative. Will never, ever take this again!"
