EffexorXR withdrawal needs to be handled very, very carefully. First, I tapered off of it. Gradually cut my dosage, even counted the little "balls" in the capsules. That's how careful I was. I still have headaches, the electrical zaps and a few headaches. I was taking 75mg daily. If you're trying to "cold turkey" it, please don't. You didn't say how you're going about this but TAPERING is the only way to go. Does your doctor know you're going off of it? Some say that Prozac helps you get off. I just tapered and tapered and tapered til I was off of it. It took months. Come back and check in with us. Good luck, Pat
