sinusitis
"The first three days on Avelox were difficult. It made me feel disoriented, dizzy and sleepy. I had to rearrange my days to accommodate a 2 hour nap everytime I took it. I got used to the medicine by day 4...so give it time. It cleared up my sinus and double ear infection which persisted after full courses of both Augmentin and Bactrim. Also, I did not feel better until about 4-5 days on the medicine, so don't feel discouraged if you don't feel great right away."
