bronchitis
"I started my first dose of 750mg last night before reading the adverse side-effects!  Big mistake.  I only slept one hour, which was 4:40am to 5:30am and it was fitful.  I feel extremely energetic, even hyper.  I don't even feel tired! My face was getting red around 9:00am and now my face, neck, chest and shoulders are bright red and painful.  I feel like I'm super sun-burned.  I called the pharmacist and she told me to take some Benadryl immediately and call my Doctor.  I'm waiting on him to return my call.  It doesn't matter since I don't plan on taking a second dose.  This is really a very powerful antibiotic and I my breathing feels much better even after one dose.  If I wasn't having such a bad allergic reaction, I would recommend this medicine."
