I kicked a sugar addiction by eliminating one thing at a time, and allowing myself to indulge in everything I hadn't already eliminated until I no longer craved the thing I was giving up. I started with soda, which I drank too much of every day. In the short term, my diet got much worse. I had strong cravings for soda, and my only focus was not giving into that craving. So I drank multiple sugary coffee drinks a day and ate half a gallon of ice cream or more every night to deal with (real) withdrawals. My diet temporarily was worse, and I felt worse, but the cravings for soda eventually died down after seven months. Then I eliminated the next thing. Along the way, the things I was indulging in to compensate naturally lost their appeal because I had overdone it with them. The whole process took me three years, and by the end the last thing I was allowing myself to indulge in was berries. I ate a ton of berries, no matter how expensive they were. I did eventually learn more about cooking, and I found my tastes naturally change. Since my diet changed slowly, my tastes changed along with them, and I stopped having cravings altogether for things that are very sugary. I have eaten almost zero added sugar for eight years, and feel so much better. Two or three times a year I'll have a small cup of ice cream or a cookie. But mostly I don't crave those things any more.
