bronchitis
"I was prescribed 10 days of clarithromycin for a respiratory infection.  Since Day 3, I've been experiencing a lot of fatigue, abdominal swelling/discomfort/pain, intermittent diarrhea, constant severe heartburn, and a constant, nauseating taste that keeps me awake at night.  It's also triggered the worst asthma attack of my life (probably because of the heartburn).  Each day is worse than the previous day, and it's unlikely that my doctor will want me to suffer through the full course.  When my doctor and I are done treating this bug, we'll get to focus on treating the damage this drug caused."
