insomnia
"I've tried numerous prescription sleep aids.  I'm on 50 mg of Adderall throughout the day so I definitely have trouble winding down at night.  Ambien and similar prescription medicines only made the insomnia problem worse, buy adding hallucinations to the mix.  A friend recommended I try Melatonin.  It's fairly inexpensive, and if I take 3 about 30 minutes before bed I have a full nights sleep and feel rested in the morning.  No weird side effects, like I experienced with the prescriptions I've tried.  Works much better than Unisom or Tylenol PM.  I suggest it to everyone I know having sleeping issues."
