What is the best way to kick a vicodin addiction?

That depends: Factors to take into account in an evaluation would include: reasons why taking vicodin, how many per day, how long, other addictions, other med/psych problems, etc. Generally, getting off the medications is the easy part, either by tapering down or by using Buprenorphine (under supervision). Addiction treatment typically requires a long-term, 12-step program or something similar &/or a therapist.
