I have talked to a couple of vets that use medical marijuana to help them sleep, they swear by how well it works for them.

I have also talked to individuals that sleep with the TV on, usually something that doesn't require watching. I find it works for me and I look for something to listen to and think about as I am drifting off to sleep. Also, if I wake up, the TV is on and that helps me know where I am rather than waking up feeling lost and confused.
