Just wondered if anyone else has been taking Venlafaxine antidepressant, and has any experience of coming off it cold turkey. I have been taking 225g for about 18 months, and have decided I don't like the awful side affects, i.e. sweating profusely, weight gain and high blood pressure. Has anyone got advice for me. I don't want to cut down the dose gradually, as it will take too long.
