I've been off the stuff for about 4 years, and I don't miss it at all. I'm actually a much better programmer without it - I don't get sucked into unimportant details, I have a more realistic sense of what I can and can't accomplish, and I'm more creative. More to the point, I have a life outside of a little bottle of pills now.
I got off of it after talking to some people who'd also gotten off - this helped alleviate my fears that I would have to give up my sweet programming career, and re-framed the problem as a matter of underused and atrophied motivation and willpower. It wasn't easy, but with a lot of love and support I managed to quit for good.
