Like the others have said, it does give side effects to start with.

I got very hot, dizzy, naseaus and felt a bit rough for a while, but then after discussing this with my psych they put me on the slow release version (i think this starts at 150mg) and most of the side effects went.

If you miss a dose even for one day it makes you feel horrible. I did it a couple of times, once I couldnt walk properly because I was too dizzy, and it made me sleep pretty much all day and night.

I have now come of it, which I'm starting to regret a bit, I've realised that it helped with ocd thoughts and depression, and although it didn't get rid of it by far, it certainly kept me off the edge.
