Remember that we are not professionals here (mostly, at least). Generally you should do this together with your doctor, therapist, psychologist or whoever you are seeing and as have been mentioned here, never cold turkey. If the main reason is mostly to get high, I would personally highly discourage it. Your mental health is much more important than that, even if I know some people find some needed relief with getting high. You should be considering your long-term interests tho. And even if you would, these medicines should not affect the activity of getting high nevertheless, unless you are talking about psychedelics.
