night terrors
"Without 5 mg. of Valium shortly before bedtime I awake in 20 minutes to two hours with an anxiety attack that keeps me up and yet unable to concentrate enough to read or even watch TV. With 5 mg. of Valium I sleep through the night! I've take it before bed for 10 years now. I've taken it  once in the daytime three or four times a year (before  a speech or flying) but otherwise have never gotten any kick out of it or craved it."
