I appreciate any help or shared stories that anyone can offer. My predicment is as follows.

One month ago I was bitten by a yellowjacket, at first it was nothing much, then a few days later I had a big splotch on my arm. I paid a visit to my doctor who prescribed to me Levaquin 500 mg. Within 24hrs I was having non stop heavy heart beat and elevated blood pressure. Also I was unable to sleep for 2 days, suddenly I began twitching every time I was about to fall asleep and if that didn't happen my heart beat was so heavy that I couldn't feel relaxed enough to fall asleep. I've never experienced this sleep problem before, and sadly I have been having the same problem every single day for the last month.

I went to the hospital and they couldn't see anything irregular with my heart and recommended that I see someone about anxiety. I was later told that possibly the Levaquin caused a chemical imbalance in my body and now my body won't shut off my fight or flight response unless I balance it with Benzos (lorezapam). I have now been taking .5 mg every 6 hours for 2.5 weeks. I still feel like my body is in an uncontrolled state of fight with some relief from the benzo. Its hard to believe that my body will not correct this state of anxiety in over a months time, I've lost 10 lbs and my heart rate is 10 beats faster constantly.

I don't know if this is truley some crazy anxiety disorder caused by this chemical imbalance or if I have some underlying illness that is causing my body to stay in a constant state of stress. Any help would be greatly appreciated
