It helps me with a certain type of mania. Like sometimes I get this super irritable mania and it is the only thing that helps. It actually like makes me into a super nice person, very attentive (only when I am in that state). It is last on my list of vices I want to be rid of...after food, after alcohol, after prescriptions. I believe it is the least harmful of all those things (for me). Sometimes though when I am manic I abuse it or I am depressed and I use it even though it isn't helpful. It would be nice if it was just legal...not medical, but just legal.
