Many addicts decide at the start of the new year that they are going to be different. They will try harder to overcome an addiction or stay sober. They'll quit drinking, smoking, etc cold turkey. That though is nothing more than self-deception. Nothing changes overnight. If you had cravings last year then just because we are in a different year doesn't alter the fact that your body will still want the substance that you've been abusing. The only way to go about conquering an addiction is making a firm decision not to do drugs again, now. Procrastination doesn't help. New year resolutions don't help. The action you take NOW is what counts. For all who'll be fighting their addictions this year, I wish you all the best.
