In the beginning, keep saying NO, as many times as it takes. Say things like "I don't do that anymore, that was the old me!" Keep saying N.O.P.E., as many times as it takes, over and over again, for every craving. Do this, and after some time goes by, you won't have to say NO anymore, because once enough time goes by, YOU WILL NO LONGER ASK THE QUESTION. Keep saying no, and the doubt and hesitation will disappear in time.
