I had the worst experience I've ever gone thru. I was on it I think for a month, maybe a little longer. I think what I went thru was akathasia from what I have heard people describe. I made it up to 40 mg my pdoc put me on congentin and that didn't work even at 20 mg. he said for some reason my body didn't metabolize it right. I was on med leave for 2 1/2 months because I was so messed up. My OCD went completely out of control and I'm still having those problems and this happened last July. I've heard either it's pure hell or a god send. Good luck to you, I hope it works out. Trying new meds is always scary because of the unknown.
