narcolepsy
"I've been taking dexedrine spansules 15 mg 2 pills at a time, 2-3 times a day for about 30 years for narcolepsy.  I'm currently 57 years old.  If it weren't for this Rx i would probably never leave my house.   Through the years i have tried various alternative meds only to find they don't work as well.  Among the alternatives tried are Adderall (made me actuallyy violent); Provigil (absolutely ineffective); and Nuvigil was worse than ineffective...because it gave me the sensation of being high. So i thought it was working and i got behind the wheel of a car...bad idea.  Changed back asap.  Been on the same dosage for 20 yrs.  Side effects:  for 10 min every day get bad dry mouth and anxious.  Cost is prohibitive."
