narcolepsy
"I was diagnosed with Narcolepsy about a 2 weeks ago and I have been taking Nuvigil for about a week. I have to admit it works. The urges to fall sleep are there but I have a choice now. I still sleep at night. About 7-8 hours, but I still wake up frequently. The only thing is, I get headaches and my mouth is really, really dry. I'm not thirsty, I am hydrated, I drink plenty of water, but I can't shake these two symptoms. So either I enjoy being awake and deal with the side effects, or I quit the medicine, and continue being tired. The first two days on it was great. But after a week, I feel sleep deprived, but I am still awake. I am waiting on a medicine to help me sleep better at night. So I will continue to give Nuvigil a shot."
