I started getting sick on October 16 and was given a phone call got the 22 letting me know that I got the H1N1 virus after the virus was gone I had a very bad sinus infection, prior to this I had never gotten a sinus infection, and was given Avelox, I have diarrhea and vomiting on and off, and I keep forgetting everything.I have taken it for 9 days and the doctor called me to take it again for another 10 days. I am definitely not taking it again thanks to reading all of this. I really don't feel that this medicine helped at all for the sinus. I have been breathing vapors and used a lot of herbs I think that this has helped out more.
