I have mood charted for many years. It is one of my most closely held beliefs...my pdoc looks at it mostly to see if I had to take Klonopin. I take it as needed and she looks to see if I need it.
I just started Mood Tracker.com and it records the minimum information. There is a place to record what is going on that day too though..it is better than nothing and it bugs me by email to do it every night.
I see my pdoc on Monday. I am going to mention some of the great ideas you all have had.
