Total fog-brain - PLEASE HELP!!

I had no idea where to post this so I did a search and this is where most of the posts regarding "foggy brain" showed up and so this is where I decided to post.

A little history first. I had prostatitis and was on Cipro and Levaquin for over two months (this has been just recently) A few days after my last dose of Levaquin, I had a HUGE panic attack and a few days later, a second one. Now, as a long-time sufferer of anxiety, OCD, Hypochondria and depression, this has'nt been my first experience with a panic attack and I'm sure it won't be my last because they run in my family but I'm now wondering if perhaps the Levaquin had something to do with these last two.

Also, just before the panic attacks started to come on really strong I had a mild sore throat that last several days and I did'nt feel so good. Ever since then, my mind has felt what I can only describe as foggy, spacey, inner-ear like dizzy feeling, mind not sharp, thinking not clear, mind feels like a fuzzy tv picture, syrupy, stuporish, soupy, swimming, scrambled, feels like my IQ has dropped 30 points, anesthetized - like my brain has been either pickled in brine or injected with Novacaine or something and my thoughts are somewhat disorganized along with mild memory problems. I am male and in my mid 40's, don't smoke, drink, etc. What is this and what does it all mean?. I mostly feel this way in the evenings and it seems that it's worse when I drink more than two cups of coffee a day. I also get these breif, sharp headaches that come and go.

Am I going nuts?. Do I have mad cow or something?!?!?. Small doses of Lorazepam don't seem to help and Xanax has a horrible "rebound" affect that makes my anxiety even worse when I come down off of it. Anyone else here have the same problem(s) I'm experiencing and how do you cope?.

- Thank's
