insomnia
"My doctor prescribed this yesterday because I have had horrible insomnia.  My girlfriend warned me that she had taken it years ago and it made her feel like a zombie the next day, on top of horrible nightmares.   Unfortunately I had the exact same experience last night.  I took the medicine at 8:30pm in hopes of being asleep by 9, 9:30 at the latest as I am up at 5am for work.    Well, 12am rolls around and I am still wide awake in bed, but crazy dizzy and out of it.   It did absolutely nothing to help with my mind racing.    I finally fell asleep between 1am or 2am and had horrid nightmares to the point that I would wake up in a sweat, go back to sleep and have the same nightmare all over again.  This morning I feel dizzy and have no focus"
