anxiety
"I've had generalized anxiety for about ten years, with some panic attacks.  Ended up in the ER twice in three days and saw a Dr. He prescribed hydroxyzine 25mg twice a day. Being fearful of pills, it took me a few days to give it a shot as I know many people with high anxiety are afraid of pills also and effects. I started slow and took 10mg and besides a few hot flashes an hour in ,it made me tired but relaxed. I slept fine and had no problems. I took another again today, same dose and was tired not long after. This was during the morning and I ended up literally going in and out of sleep for hours on end, hearing everything but also not awake, very strange. Anxiety a bit better, yes. Give it a try"
