Biker Kush from Karma Genetics can put people to sleep. My tolerance is pretty high, and this is the only one I trust to help me sleep in emergencies. It also doubles as a magnificent smoke. My favorite is to take it in a one gram joint with a gram's worth of freshly pressed rosin (of Biker Kush of course) wiped on the inside of the paper. Nighty-night
Come to think of it, I give my insomnia patient this one. I often forget about that because half an ounce for a light smoker has been lasting for a good 9 months now lol. All he needs is a one-hitter dose and he's resting like the dead. I'm actually writing this as I'm waiting for the Biker Kush rosin I'm vaping to put me asleep.
Best of luck, I've seen first hand what this disorder can do. I hope you get your life back as quickly as is possible.
