With me, when I'm hypomanic, 1 of 2 things will happen ::

1- I'll act like a 5yr old who had waayyy too much holloween candy. I'll be jumping off the walls, rocking out to music, laughing hysterically, gasping every five seconds and going on a rant about one thing, then another, annoying everyone around me, laughing laughing, and laughing. My friends ask me if my water is spiked, and on one occasion even try to administer a drunk test because they weren't sure how I could be sober and act so crazy.

2- I'll suddenly HAVE to do something-- like a huge project. the alst time was this weekend when I turned a nasty old basement workshop into a georgeous pink lacy bedroom.
In the past I have written jaw-dropping essays, spend the entire night cleaning my room (its a bigger task then you would imagine, lol) etc. I feel the need to take on a huge project, and I'm not satisfied until I've done hours of work and an amaazing job.
