insomnia
"This medication is worse than useless. It actually seemed to keep me awake and caused me to wake more often during the night than I normally would. 

After the third night I tried taking it with a xanax (the xanax would normally be enough to help me get to sleep) and it still kept me awake! I'm glad I got this medication as a sample because I would be really angry if I'd had to pay for it."
