if the zyprexa is the only thing you have changed, chances are, the feeling is from it. it may go away in a few days and the med adjusts to your system. if it doesnt then talk to pdoc about reducing if the med is working or changing to something else if it isnt. remember, the dr works for you. there are tons of bipolar meds out there. you do not have to stay on anything you dont like. it took me over two years to find the right meds. i was constantly changing because i refused to put up with side effects or meds that just sort of worked. now i am on meds that have no side effects that completely stabilize me. drove my pdoc crazy changing all the time, but i wanted what was best for me. you have to be willing to advocate for yourself.
