I don't know your specific drug but my experience getting off ATIVAN taught me to reduce very very gradually by 10% weekly ... which meant careful pill cutting. Exercise, meditation and boring glasses of water helped me control the side effects...coffee, my drug of choice, made it even more difficult. Now, two years later...I am a different person..

The instructions for your drug states"A gradual reduction in the dose, rather than abrupt cessation, is recommended whenever possible. In clinical studies with Effexor XR, tapering was achieved by reducing the daily dose by 75 mg at one-week intervals. Individualization of tapering may be necessary [see Warnings and Precautions (5.7)].
