I always had the exact same problems with AD's. My Dr. Just recently put me on Buspar for Anxiety. I do take Xanax as needed. I have not had any side effects with Buspar as I started at a low dose and moved up a little very slowly. It has been the only med I have been able to tolerate for any length of time. It is a mild med, so I do not feel like a Zombie. At first my head felt tingling about 30 minutes after I took it, but it went away quickly and after all the side effects I had suffered through, that was nothing. Good luck finding a med you can tolerate, I know how frustrating that can be, keep trying different things, you will get there.
