Thanks TRNRMOM. I am glad for you that you do not experience depression. That is always nice to hear. I tend to exercise in the evening because that is when I have time away from school, but maybe like you say morning exercise is better.

Unfortunately, depression is a part of my bipolar 1 life. Exercise is one of weapons against depression. But I'm wondering if it may also work to speed up my brain a little too much. I have had 1 manic episode 2 years ago but have never come close to another manic episode. I do however experience patches of sleep disturbance which are generally coupled to decreased hunger, a feeling of being warmer than usual, and sometimes a "wired" feeling.

I am afraid because I have been told depressive episodes can follow such "hypomanic" periods.
