narcolepsy
"I tried to write a lot more, but the space is limited. I'd tried ADHD medicines and loading up with caffeine, but nothing seemed to work to manage my excessive sleep cycles. I stumbled across information on Provigil, and asked my doctor if I could try it. I was skeptical because I have eczema, and I have to be careful about the medications, foods, and external allergens I'm exposed to. I began at  the lowest dose once/day, and increased to that twice a day after a year and a half, because it seemed the effectiveness was decreasing. I do take breaks from the meds, usually for a day or two, but I've had to for months (cost) and haven't experienced noticeable withdrawal symptoms, like with all the other chemicals."
