It's 12:30 am of my 4th night of no sleep since I started taken Levaquin, I can't believe what I'm reading, I just got up of bed straight to the computer to find out about side effects of medications, I thougt I was going crazy, now I know It's the F... pill...My heart is racing, I'm sick my sinus infection got worse, the first day I felt nausea, dizziness and felt like I was going to pass out...I can't believe it.
