Heart keeps symptoms and conditions

I have ben on Levaquin for 6 days now I was given a 10 day supply of 500mg. once a day. BUT I am not taking it any more . I can't sleep even taking Ambin, my heart keeps racing and I feel depressed. My legs feel like something is tickling them and the muscles get jumpy every so often. I never had these troubles before taking this drug. I have taken a few this will fix you right up type meds. but whew this one needs more study.
