Yeah, I agree. Mood charting can help you figure out your triggers, as well as figure out which symptoms you tend to display right before an episode. You can also figure out how long your episodes tend to last.

The only difficult thing about mood charting is sticking to it. I've always had issues sticking to it, as I do it on and off instead of doing it everyday. (I tend to think, "Oh, I'm fine... I don't need to do this anymore!")
