Thank God I found this site also! I thought maybe I was crazy! I have been taking Levaquin only a few days. I take it with dinner thinking it would help ward off side effects-yeah right. I feel very "drugged" about an hour after I take it, like I can't wake up for anything, but then I wake up in the middle of the night and can't get back to sleep! I aslo have been very achy in the legs and back and thought something was really wrong. Thanks to all who posted their expeiences, at least I know I am not crazy and I will not be taking the last 2 doses! Oh, I also have that metal taste-yuck! Good Luck and Health to everyone!
