narcolepsy
"I have been taking Nuvigil since I was diagnosed with Narcolepsy 10 months ago and I finally feel like myself, I was barely functional without it. When I first started I had some trouble with side effects; sleeplessness, anxiety, and jitters.  What worked for me was starting at a much lower dose and working my way up to the dosage I needed.  I do several things that I think also help me get the most of Nuvigil.  1) I take may medicine at the same time every single morning, even on weekends, 2) I drink a lot of water, if I'm dehydrated at all my heart rate goes up, and 3) I take CoQ10 and B12 (both recommended by my neurologist) these completely got rid of the anxiety problems I was having.  It took sometime to really figure out but 100% worth it."
