I have been on levaquin for three days 750 mg i feel horrible i cannot sleep i wake up soak and wet and then have chills my body aches and i feel as though i cant keep still. i have a constant headache, what i thought was going to make me feel better from a severe sinus infection has left me feeling like im gonna die. it is scarey that they allow this to stay on the market. iam not by any means taking the rest and feel like not only flushing the rest but burning it. oh yeah iam sick to my stomach and then when i do eat i have pain and nausea again. i hope it doesnt take to long to get out of my system this stuff is straight up evil. i will tell anyone who will listen NOT TO TAKE THIS MEDICINE. BEST TO ALL.
