Hi all,I haven't posted much on this forum, but I read it often, and it has helped me greatly to know that I'm actually...okay!After several years of no BFS symptoms (yay!), I had some kind of prolonged viral illness (similar to mono) this past winter. Then all of a sudden they're back...twitches, strange sensations, and worst of all, anxiety and panic attacks.I was prescribed Xanax for my panic attacks, which I had never really had much experience with, which worked for the panic attacks of course. But little did I realize just how quickly your body adapts to Xanax, and subsequently withdraws from Xanax. I only took it only a few times, when having a panic attack, or when I was feeling a little anxious. Then, suddenly I realized that I only ever felt "normal" just after taking Xanax. Several hours to a day after my last dose, I would feel all the following symptoms:Anxiety, feelings of hopelessness and doom, much increased levels of muscle twitchiness, confusion, memory loss, muscle cramps and aches, parasthesias, visual snow, night terrors....you name it, and I had it. This went on for almost a year before I realized that it wasn't just BFS, or just anxiety, but it was physical dependence on a GABA drug - Xanax.Finally I've now managed to taper, and have now finally gone over a week without taking a single one. I can still feel some of the withdrawal effects, including occasional muscle spasms in my hand, and I'm still having mild night terrors almost every night. I'm hoping these will also resolve over the next several weeks.I can't help but to think that BFS is somehow GABA related, seeing as how anxiety almost always goes along with it, and the fact that Xanax withdrawal (even after just a few pills) amplified the BFS symptoms tremendously.BFS and Xanax don't mix. My advice: only use them when you absolutely MUST, i.e., when facing a crippling panic attack. Don't take them when you're just feeling "a little anxious", or because you feel you *might* have a panic attack soon. That's what I did, and because of it, I was almost never able to feel "normal" at all for the past year! If you're taking it, and never feel quite "normal" (except just after taking a dose), it may be the Xanax itself causing the symptoms!Sorry for the long post, and thanks to everyone for all their posts here, they help tremendously!
