Well, I have bipolar disorder, so when manic (or even just hypomanic) , I have done or said all kinds of major shake the head things. Adding some booze into the mix never helped.

Speaking of booze, maybe three years after three psych hospitalizations per year, and an initial detox from alcohol, I had been accepted to receive SS disability. I was still struggling with mania or hypomania, so decided to enter training to become a professional bartender. I made it to the intro class, but it ended at that. I think I was soon after hospitalized again (or near so). Believe me that that career would not have been a good match for me.
