Hmmm, all I can add is that that sounds like me when my sugars are out of whack too. When my sugars are getting too low, often I either am in a goofy, feel good mood or else I am...er...grumpy, snappish and difficult to be around. It varies...and having low blood sugars were my first sign of CFRD. Sorry- I hope that's not it either.
Oh, and I spoke to someone the other day who has a son recently diagnosed with Type I diabetes, and it sounds like they do us the same way they do growing kids with diabetes (at least type I)- eat and compensate with insulin, but try to avoid the really big gut load of sugar foods <img src="i/expressions/face-icon-small-wink.gif" border="0"> .
