I was in the same boat you were in a while back. I had to smoke more to get it to work and help with my mood. Eventually, it got too expensive, it's illegal, and my gf wasn't going to date a pothead. I agree with you and hope that it will one day be a legal prescription at least in the U.S. it really did seem to help take the edge off my mania.

But good lock and god speed! Hopefully, you will find that Lamictal helps just as good. I'm on 200 extended release (1 pill in the morning and 1 pill at night) and it's worked wonders for me. I still get manic but it's bearable. Best of luck!
