I'm using eMoods and have noticed really interesting patterns in my sleep relative to my mood designations. It's pretty consistent on a bi-weekly basis of increasing mood/decreased sleep (5-6hrs) then wham.. mild depression and then a few days of 7-8hrs). I've never noticed this before and right now I have no idea if it's the antidepressant causing mild cycling. The hardest thing for me is distinguishing between baseline mood swings and significant mood swings. Depression is easier since the flags are so obvious.. tired and those suicidal type fantasies (not the serious type recently)
