I have been ok 50 mg Pristiq for two weeks and 2 days. The side effects were building to the point where I would rather be off Pristiq than on it. I stopped cold turkey yesterday morning. I ad my plats dose Monday, two days ago. This day three and I am very ill with nausea, vomiting, dizziness, vertigo, I can hardly walk.n Inam trying to keep up with my fluids. My GI tract is miserable with diahhrea and cramping. Inkeep getting headaches and my head feels like cement. My Pdoc is on vacation until next Monday. My GP said to taper gradually and so did the on call PDoc. Problem is there is no smaller dose than 50 mg to taper too. FDA said not to alternate days on and off. How can Inhelp myself and how long should Inexpect these discontinuation symptoms to last?
