I'm with you. I hate that Last time I got angry hypomanic, I was sitting at a lunch table with some friends, and I kept Screaming Arrgghhh!!! and punching the table, and swearing like a sailor, and everyone kept asking what was wrong, and I answered "nothing! That's the PROBLEM!!"
... and then they pulled my hair, (softly and friendly) so that there would be something wrong, thus solving my problem.
Didn't work.

Good luck, and don't be too hard on those cheerios
