I have no idea what the recommended way is....but I just stopped cold turkey 4 days ago. The first 2 days I had headaches and nothing since. I would talk to your doc though and see what they say on the 'proper' way.
I was on it for 3 years and just quit cold turkey one day. I don't remember any side effects for stopping like that. Consult your Dr though I didn't and I'm sure if I did he wouldn't have said just stop.
