I was on Effexor 150mg for about 3 years and decided to get off. My doc and I weaned me off slowly over a month and I took my last 37.5mg pill a week ago. Aside from being dizzy, I didnt experience anything too bad. But that was because my doctor advised me to take Vitamin b complex and antihistamines (benadryl) and I really think it helped! Now I am almost done with all the symptoms, just a little dizzyness here or there. Its possible to get off this drug!
