I'll be honest on this one too. I've been smoking marijuana for years - usually at night so that by the time I go to bed I know I'll sleep well. Otherwise I only sleep a couple of hours at a time. When I am cycling and in a depression mode, marijuana helps me out of my funk. It's when I'm manic that I don't feel the need for it. Where I live we do have legalized medicinal pot, and I am eligible for it because I also have glaucoma. I can tell you the medicinal types are very strong - very little is needed. I'm getting a bit concerned that it's causing me to disassociate more than usual. I don't see myself stopping completely any time soon.
