I am almost 50 years old and have been on my meds about 6 months.
I get what you are saying about being normal. It is a big adjustment and can be frustrating.
I personally miss some of the more productive portions of mania, but unfortunately you don't get to pick out the parts of this disorder you want to keep.
For me, I know the meds are the best route to go. But there are other people on this site who seems to be able to manage their BP without meds.
