Hmmm, I was gonna suggest k-pin. I haven't noticed any effects but then again I was on 2mgs of xanax for the better part of 7 years. How long have you been taking the k-pin? If you just started the side effects might go away.
Yeah, that can mean that your dosage is too high. Buspar also works on anxiety, but takes a while to build up. It won't depress yourself as much as a benzodiazepine does. It might be something to ask your doctor about.
