I am diagnosed with bipolar and ADHD. Have you ever heard of Dr. Amen? He believes there is more than 1 kind of ADD/ADHD and one of those is called a "Ring of Fire " and it is thought to be closely related to Bipolar.
It appears that since you are not losing sleep and are not suffering from grandosity that you are not experiencing classic mania. I would research ring of fire ADD and see what you think about that. good luck.
