Hydroxyzine
"I started taking this about a month ago because my anxiety gradually got so bad that I didn't sleep for a week. The first few nights it worked amazingly but it was difficult to wake up but then I'd be very alert and awake all day. However, my doctor told me to take it twenty minutes before bed and I would not feel the effect until much later. I actually took my dose about 40 mins ago and I'm just now starting to relax."
