anxiety
"I have Cluster Migraines so the doctor put me on Topamax, after about 2 months I developed anxiety symptoms and a rather hateful personality so they added Buspar to take  the "edge" off. It has worked well for me but I can tell when it wears off. I'm on a low dose so it just may be time to adjust( 5mg twice a day ). All in all very satisfied with this medicine. It does make you dream vividly but that doesn't bother me."
