narcolepsy
"I have been taking Dextroamphetamines and/or Dexadrine since 1993 when I was first diagnosed with narcolepsy. The main side effect for me Is dry mouth and talking to much. If I take the medicine within 8 hours of bedtime, I may have slight problems going to sleep because I'm still thinking too much. Other than that, I'm as far away from insomnia as I can be. I have done 2 sleep studies while taking this medicine and I still go to stage 4 sleep in less than a minute, at will. Before this medicine, I was never able to drive more than 30 minutes, I couldn't go out to peoples homes, or watch TV, or go to the movies. Even when I played in a rock band I was falling asleep during practice. This is a miracle drug for me."
