I've become very dogmatic with my doctor. She put me on a preventative for migraines and I started studying the side effects and they weren't good. I told her I was going to wean off of them. It was scary to know I could possibly end up with severe vision problems and they killed my stomach!

The only problem I've ever heard about with Effexor is coming off of it. You have to be really careful and do it with your doctor's guidance.
