I forget to say it was Venlafaxine XR I was on. Its a bumpy ride when it is cut or stopped. There are some real horror stories from newspaper articles about people coming off Venlafaxine. But if you switch to another anti-d, the new drug replacing it should prevent the most debilitating withdrawal symptoms so I would say try not to worry about it, if the Venlafaxine is working for you at the time. Even though sertraline is an Ssri and Ven was an snri, i coped perfectly fine.
