just taper off, man. I have a family full of people who use them. If you're running 40 mg a day, just cut down to 30 a day, then 20 a day, then 10 a day, and then every other day until you barely notice them. You'll feel alert and alive again as well.
Stopping suddenly can kill people or make them crazy... i've seen folks do that too. IMO, the withdrawal is probably the scariest thing of SSRIs.
