About a year and a half ago I did a sleep study and was diagnosed with narcolepsy
. First, they advised me to try several different stimulants, but each one made me go insane. I shook constantly, I went from smoking a little less than a pack a day to 2 full packs a day, I talked constantly, I was panicky, etc. Then, my doctor suggested Xyrem. Here's where things got bad. I took it as prescribed, slowly building up my dosage, until I got addicted to the feeling it gave me before I fell asleep.
