Maybe you should remember that quitting alcohol/drugs/meds actually requires you to go through some pain. Do you expect it to be a happy fun ride down a rainbow slide and then you land in a bucket of cotton candy and naked ladies?
Cutting substance abuse out of your life is painful. You should expect pain, and finding ways to cut corners isn't going to do you any good.
That said, always consult with your doctor etc, make sure you're not in danger of having a seizure or stroke and whatnot. Good luck.
