I definitely feel foolish after some of the things I've done when manic. But then, sometimes I feel foolish about things I've done when I'm not, so at least I can point to a reason why - even if it doensn't change what I did. And I always tell myself I won't do anything like that again even if I do get manic - but, of course, when I get manic it all seems perfectly reasonable. I think all we can do is try to keep things on an even keel (and for me that usually means medication) - sigh...
