I don't know how long it will take but I have been on this antibiotic for a week. I have actually gotten sicker. I have had the nausea, feel lightheaded, dizzy, down right goofy. I have had a few breathing problems with it. The first day I vomitted five forceful times...thought it was the sinus or bronchitis. They changed my antibiotic today to Augmentum. I was being treated for a recurring sinus infection and bronchitis. They took a chest x-ray for pnuemonia. This drug has made me feel awful. I had a piercing headache almost every four hours and just kept taking advil every four hours. Hope you feel better. I will never take this again. My Physicians assistant said she cannot take it either. Good luck
