One of the main reasons I resisted my DX, was because ALL of my episodes have been triggered. I never just "get depressed" out of nowhere, neither do I just "go manic" out of nowhere. Without some sort of trigger, I am basically normal. My dad is the same way. He used to be so crazy, he was hospitalized 6 times. He has been totally stable and med-free for almost 20 years simply because he eliminated all triggers from is life.
