Hydroxyzine
"I have psychogenic itching. No other way to describe it. I have to scratch, my hands, body, everywhere! I also have anxiety and depression, so I told my doctor and therapist about the horror of this itchiness...I have been taking this medication for a few years, and I can't take it when I have work or school...I'm totally groggy the next day. It doesn't help now as much as it used to, but for days when I'm suffering; I have to take it."
