I had to quit Prozac very abruptly - cold turkey - and it was a seriously fucked up few weeks. I remember the zaps, like being randomly tazered, with bonus hand twitches and tics. I find it disturbing that it happens even on a rational 'weaning off the meds' schedule. This stuff has so goddamn many side effects it's scary.
FWIW, it does get better rather quickly, and having my creativity back was totally worth it. If you do need another med, I found Welbutrin to be much more manageable, with fewer negative effects, and very easy to quit. YMMV, of course.
Be well.
