I have lots of experience with cannabis and sleep but little advice to give. The operative phrase is YMMV, your mileage may vary.

Self medicating is fraught with obstacles and pitfalls. But in my case, a man's gotta do what a man's gotta do. Cannabis has helped, but now I'm trying to leave it behind me.

Fortunately, I have doctors that will listen objectively about my cannabis use. They don't (can't) say much due to the lack of double-blind studies, but this may be changing as more reliable evidence starts to emerge.
