I have noticed it affecting my temper too! Interesting. I find myself arguing with people and making snide remarks. I am holding back when I feel that way or I'd be saying a lot more.

And the appetite effects are unsettling. It's like a voice inside my head says "FEED ME - FEED ME NOW. ICE CREAM - A WHOLE PINT & A LARGE PIZZA, TOO." I usually have a talk with the "voice" then give it some yogurt. Then I fall asleep while it's still muttering about how it could wipe out a whole chocolate cake.
