I was sugar addicted for years. Not so much carbs, but sugar. I'd drink up to three liters of soda a day, plus super sweet tea and other sweets. But close to a year ago I realized I was killing myself, so I started by limiting myself to one 12 oz can of soda a day. After just a few days I found it pretty easy, then even started skipping it altogether some days. Now I find it's almost too sweet and I don't crave it nearly as much. I also have cut the sugar in my tea and eating fewer sweets, and I really find most stuff too sweet now and just want a small amount or none. It's amazing how fast habits and cravings can change. I've lost some weight and generally don't feel as sick now.
