sinusitis
"I've suffered chronic sinusitis for years and after building up a tolenrece for most antibiotics I was put on clarithromycin. After the first day I was experience severe diarrhea and the awful taste in my mouth, it's now day 4, after the constant chemical taste (absolute torture) and waking up two nights in a row from nightmares I quit. Done taking this and will NEVER take it again. Wasn't helping my sinus infection anyways."
