Biaxin is by far the worst thing that has ever happened to me. I was presecribed it two days ago for a sinus infection and bacterial pneumonia. My heart beats extremely fast at night and it is impossible to sleep. I woke up this morning to violent dry heaving, while ever bite of food is a struggle to keep down. I have been sick for 3 weeks prior to this, and I can honestly say that Biaxin has made me feel so much worse. It really makes me feel like I am dying.
