Levaquin and drs office

I took levaquin 750mg as prescribed yesterday, after leaving my doctors office at 330pm ( june 18th). along with calrinex d (1tab) and a tsp of tussionex suppension syrup and 4 nose shots of astelin in increments of two over a 4 hr period of time. I was awake a majority of the night unable to sleep. But had some bouts of sleep. This morning (june 19th) I awoke at 930 am forced awake due to an appointment, and took 550 mgm of levaqin and the array of other drugs, around 12pm I noticed a headache and believed it was due to the exertion of coughing so much, my appetite is non-existent and around 6pm I felt flushed and sweaty, however this feeling subsided. I am now in hyper drive, I want to fall asleep but when I do my throat has the sensation of being choaked and then I have this odd gush or air emmited nasally which awakens me from the doze. My left corotid arrtey was tender and my heart is palpitating. While my sinus infection is almost gone I do not think I will be continuing this medication. There will be a call made to my physician at first reasonable light, I am sure I will be awake.

Took leviquin 500 for 8 days before I realized what was happening to me. Side effects included: severe panic, altered mental state, constant sleep, loss of appetite, pounding heart rate. After 2 trips to the ER no help was provided. I stoped the Leviquin early (was supposed to take it for 3 wks) and immediately started feeling better. The anxiety is much less but still present and I still sleep all the time.

Has anyone had similar experiences and, more importantly, how long does this last?

Please help!
