Narcolepsy
"Took methylphenidate SR (Ritalin sustained release) 100 mgs a day for years for major depression, was still tired, could still sleep at anytime, but not too bad. Dr retired, new Doc doesn&#039;t want to prescribe that he switched script to Adderall 90 mgs  a day. Worked at first but not well, now it is worthless. I can hardly get out of bed and it is almost impossible to stay awake all day. Did the Sleep Study a few weeks ago and Dx with Narcolepsy w/o cataplexy, prescribed Modafinil to take with the Adderall, a little better. In my case the Adderall must go. Very good that it works for others, as no one wants to feel like they are sleeping their life away."
