I have been sick for going on 5 weeks now. I started with Bronchitis and was put on a Tri-pac (Arithomycin) for 3 days. After 10 days of my last pill started with what felt like a sinus infection. My doctor prescribed Levaquin. I've only taken 2 pills and have experienced loss of sleep the first night, EXTREME dry mouth for the last 48 hours and a heart palpitations. After reading the info on this site I have decided not a good med for me to take.
