I never really get a temper when manic. That's interesting that it changed for you. The only time I would get a temper is when going from manic to depressed. Sure I was able to do tons of work, be super productive and lots studying when manic. But it wouldn't last that long, then once I get to the depression side I wouldn't be able to do any of those things. So in the end my time being super productive didn't really mean much.
