Withdrawl symptoms from hell. 300mg - 50mg in two weeks.

This was the reccomended timeframe from my psychiatrist. I've currently been on Pristiq for three years.

Holy fuck. This is the closest I have ever felt to dying.

I don't know if I have come off it too quickly, or maybe I have a bad tolerance, but this is like nothing I have ever experienced before. Intense nausea and brain-zaps, sweating, brain-fog, and this overwhelming horrible feeling I can't quite describe. I've been crying on and off for days now. I don't know what to do.

I'm supposed to be switching to another medication, since it seemed my progress has plateaued, but man, I don't want to EVER feel like this again. I can't handle this.
