I completely agree with this. Everytime I ever experienced hypomania, I turned into the person that I thought I always should be, outgoing, productive, confident and sociable. Sadly, I always built a tolerance to whatever drugs induced that hypomanic state and I too, wish that I could maintain long term hypomania. People used to say that taking memantine along with a stimulant such as adderall would help prevent/reverse tolerance to the dopaminergic effects of the stimulant for long lasting benefits. Some reported success in preventing tolerance, while for others it did not work. It would be worth looking into this and giving it a shot if tolerance has been an issue.
