Follow-Up: My doctor prescribed Provigil and a CPAP machine for my sleep disorders. He seems to have been in on the initial Provigil study. The CPAP machine made absolutely no difference. After two weeks on 200 mg of Provigil without relief, my doctor said Provigil usually works for most people at 375 mg. He doubled my dosage to 400 mg. He also insisted I should continue using the CPAP machine. Still no relief!!! My doctor insisted that both the CPAP machine and Provigil works and hinted I just wasn't aware how much better I was feeling. I finally got my sleep doctor to grudgingly prescribe Ritalin and diagnose me with DSPD, Delayed Sleep Phase Disorder. My doctor would never have prescribed Ritalin if I hadn't asked for it. I felt an amazing difference in how I feel immediately the following day. For the first time in my life, I'm waking up BEFORE my alarm clock feeling rested every day. I now have the energy to do every thing I've neglected over the years due to lack of energy and sleepiness. I now have the energy that I feel most normal people have and take for granted most of the time. I believe my sleep doctor gets kick-backs when he prescribes CPAP machines and Provigil. He became very irritated with me when I told him neither were working and insisted I should continue using them anyway. I hated wearing the CPAP machine and had no desire to be strapped to life support every night the rest of my life, especially if it provided no obvious relief. I was ready to commit suicide because I felt so bad and none of my doctors had any clue of how to help me. I am coming to the conclusion that doctors really have no clue how to treat most problems. They are very good at broken bones and cuts, but when it comes to things that don't show up on x-rays, cat scans, or have visual clues of any kind, they are just blindy guessing on their treatments. Sadly, they won't admit that they are blindly guessing because I believe they have this god image to maintain. I went through 2 years of testing, saw dozens of specialists, and took a multitude of drugs only to feel worse than ever. If I hadn't asked for Ritalin, I probably wouldn't be alive today. P.S. My primary also prescribed Welbutrin the same day I was given Ritalin by my sleep doctor after stating he was running out of ideas. There is a very good chance the Welbutrin is enhancing the effects of the Ritalin OR the Webutrin is responsible for my dramatic improvement. Right now, I am feeling so good, I'm not about to try to find out which drug is doing what.
