i had one noticable one the other day. Talking really fast, running around, doing anything active like jumping or spinning. Happiness for no or little reasons. Really hyper. You're like in love with life and the world. You get distracted really easily. I was talking so fast about constantly changing subjects that my mind couldn't even sit still on one subject. that's about all i can think of at the moment but there is a link at the top of the page that should give you more information.
