Let me preface this by saying I am unmedicated, but smoke pot daily sometimes and sometimes not at all. I have gotten anger like you describe and self-harm a couple times a year. Mostly I just have longstanding depression. Recently, I had my first manic (not hypomanic) episode. I have discovered that kratom helps lift me out of a depressive funk, but it may also exacerbate mania.
I don't know what kind of meds can be given for while you are in episode. That is what I have always wanted, something to kick the high down a notch when I can't concentrate and something to snap me out of the lows. It would be great if I could get prescription opiates because they sure do make me feel better when I am down. The anxiety meds seem to cool the ups for me a bit. Anyway, I was under the impression that drs. won't handle bp in this manner, which is why I rely on self-medication. I'd love to know if you find differently. I am really not interested in getting fat or dealing with other side effects of daily meds.
