I have been feeling good for around 3 months. There have been periods where I might have been hypomanic, but I’m just taking it all in stride. I have sleep difficulties regardless of mood state, so for me, that would be less concerning. Honestly, I’d say monitor it but enjoy feeling good. I know I can get into pathologizing my moods, especially when I feel good, and it sort of takes away from the positive for me. Obviously though, if you are truly concerned, call your doctor.
