"i deal with extreme anxiety in a lot of different scenarios likely rising out of autism.  i&#039;m on about 75mg a day, and i cannot say i have side-effects, other than waking up with a pounding heart for a few hours if i drink too heavily.  i have had such good effects from the drug to the point where i can actually see major differences in how i interact with people and events and almost see a difference in my personality (for the better) over the past several years.  i have recommended vistaril to several people."
