I just did what you are planning. I titrated myself down from 40mg to 20mg. I was hypomanic for about two weeks, then crashed. YMMV. I tried going down by splitting the 1/2 a pill, without much success. And only went a few days before I basically realized that I had done the titration ing too soon, and needed to go back on. So PLEASE be careful. I know you probably are like me and just want to pitch them and be done with it, but that is not the answer. You may end up with a worse reaction than what I had.

Good luck.
