I was on Pristiq 50 mg for 34 days and decided to quit cold turkey. It's day 4 now and I am jittery, a bit agitated and my appetite has increased. I was having crazy dreams and problems sleeping, but last night was a little better. I know cold turkey wasn't the way to go, but I couldn't take the fog I was in anymore, being on Pristiq, and my psychiatrist went away for two weeks. Hope this helps someone.
