The withdrawal is horrible which doctors don't tell people when they start them on Effexor. It is one of the worse to withdrawal from. I went off 225mg of Effexor in January and I had studied about it on the internet and learned about people using a Prozac bridge. I had tried to go off it before and it was impossible. I told the doctor that is what I wanted to do. She prescribed me 37.5mg and I slowly switched over to Prozac. I would take away a 75mg and replace it with a 37.5mg and 40mg of Prozac. I had no withdrawal and was off the Effexor in 3 weeks. I stayed on the Prozac for 3 months for residual withdraw from the Effexor. It worked like a charm. I don't know any Doctors who tell patients about the Prozac bridge but they are all aware of it. Good luck. The withdrawal is no joke.
