At Today You Can, the suggestion would be to visit a health professional as soon as possible if you feel you have an issue with addiction. This is important because discontinuing a drug without the proper information can be very dangerous. Once you are deemed to be safe, it might be a good idea to seek treatment. The American Addiction Centers suggests that you begin searching for rehab or detox centers near you by conducting a search with the Substance Abuse and Mental Health Services Administration. Be prepared to verify your income, whether you have any insurance and any need for financial support before you can enroll. Free rehab centers and public assistance for rehab do exist. Exploring treatment avenues such as these is a good idea as it may reveal detox programs and other recovery options available to you at little or no cost. There are also opportunities to defray the cost of treatment or to have it covered by another entity.
I hope this helped you understand where to go if you feel you have an issue with addiction.
