The worst experience of my life. I went thru akathasia and congentin didn't help. I was on a low dose and it didn't matter at what dose. My pdoc said for some reason my body did not metabolize it right. It messed me up so bad I was on med leave for 2 1/2 months. This happened a year ago and I am still having other side effects from it. I've read it's either a God send or pure hell.
