hypersomnia
"I have chronic fatigue due to autoimmune, mitochondrial, autonomic... I also have a (genetic) circadian disorder, Delayed Sleep Phase Syndrome & hypersomnia ( sleeping up to 12 hrs day). I can't work. I feel more alert on Modafini (Provigil) and can do more activities. It gives me mild anxiety but I'll take it over being fatigued. 1st few nights I had trouble falling asleep. After that, I actually started feeling tired at the end of the day and often go to bed earlier. As for my hypersomnia, I can't sleep much longer than 8 hrs. Once I wake up, even if I would like to, I can't fall back to sleep. I am very glad I finally after 8 years of fatigue decided to take it. Wish I did sooner."
