Sleep or lack thereof

I'll probably repeat this over and over but the one thing I love about being hypomanic/manic is not needing to sleep and yet being able to stay awake throughout the day. When I'm not in one of those states, I tend to toss and turn at night a lot then get sleepy for the rest of the day. I thought about this a lot today because I noticed after being sleepy in DBT, I was fairly alert for the rest of the day. Even in the afternoon, when I lay down, I kind of just floated along the edge of consciousness. So I wonder which way I'll be swinging...
