While I am bi-polar II and don't suffer full blown mania, I can tell when I am beginning to cycle into a hypo-manic state. Generally, I stop sleeping, my thought race, either I don't eat or I eat a ton, I feel really great, and get alot accomplished. Normally, you will find that it will start out great! You will wish that initial feeling could last forever, but then you will begin to spiral out of control. I would deffinently speak with my psychiatrist and find a good couselor to help you being to identify your signs. In addition, our friends and family always notice our changes in our behavior before we do! So ask them to talk with you, if they notice any changes and agree to listen and be polite when then do talk with you! Hopefully you are getting on some good meds, so you will have even less to worry about.
