Yes...sounds like hypomania if you're not doing anything dangerous. I had a bad reaction to effexor, shaking body, hyper, irritable. Came off of it and feel better. In fact, lamictal is what replaced it. I'm hypomanic too. Have been for six weeks, with the exception of a few days when I went on a spending spree and wasn't driving safely due to my vision being so blurry (caused by Abilify, which also was a bad drug for me).
So, I relate. I'm doing tons of projects and getting things done, my mind feels sharp, etc.
Wish you all the best and watch out for the crash (not that I think you'll have one. I haven't after 6 weeks).
