Pruritus
"I have taken Hydroxyzine for around 30 years for chronic itchy skin and insomnia. I take it only once a day - at 6pm - and go to bed at 10pm. I take only 10mg, but also about 1.5mg of Temazepam (i.e. a bit broken off a 10mg pill) before going to bed. I get about 6.5 hours sleep usually. The down side of Hydroxyzine is that it makes one feel dopey for around 12 hours and affects short term memory in this period. However, for itching there is no other drug that is so effective."
