anxiety
"My experience with it.  The medicine works great for itch relief (pruritis) and anxiety.  I have Graves Disease, this was to treat anxiety temporarily after thyroid storm.  The problem I had with it was it made me to doped feeling to function normally.  I stayed tired and experienced grumpiness and lack of patience.  I've taken Xanax, and Elavil before and definitely was able to work, socialize normally unlike this medicine, there is no way I can take it every four to six hours and function throughout the day. I've never been one to tolerate antihistamines very well, I get the shakes etc., and  experienced the same with the Vistaril.  All that aside, at night it did help me sleep, help the anxiety as it's supposed too."
