My brother burns a lot and has been diagnosed with bi-polar. He has the same thing going on with taking meds / not. Doesn't take them regularly enough. He hasn't quit buddha...and that's a good thing. He seems more self-destructive etc when not toking. But like HiProGlow says, the meds to be key. I have ADHD and I can tell you that I need my buddha meds, or I can't function.
