My sleep is the absolute best indicator of my mood. If I am getting 7-8 hours and not taking regular naps, then I am stable. When I am stable, however, I can take a nap on the weekend and enjoy it. As soon as I start having trouble going to sleep at night, I know that change is coming.

Once the hypomania kicks in, I have to take meds to sleep. Doing this keeps me from getting out of control.

When I start feeling tired and I need a nap every day, then I know that depression is on it's way. Once I tweak my meds, I can't really take a nap anymore and that is very difficult for me because it makes the day feel very long.

I know some people have a lot of success with a tight sleep schedule, but that has never really worked for me.
