I stop sleeping and eating, start sending bizarre texts and emails, and become extremely impulsive. That said, I still don't usually notice but those around me notice.

I would certainly call your pdoc as mania can be dangerous and horrible for you.

It is worth it to try to avoid it or soften the blow.
