narcolepsy
"My experience about xyrem is phenomenal. Going back, I can't imagine myself how I survived before this medication, comparing how I used to feel before taking the medication. I'm at least 70 percent feeling better. I read a couple suggestions on this website as far as not eating 2 to 3 hours before and not drink much water 5 hrs before, I will try them to see if I can get any improvement. So far my only issue is on the second dose, it wears off quick, it feels like I passed out for a couple hours and wake up to pee and that will be it but still can feel that heavy eyes just won't be able to fall asleep again."
