"Quitting" sugar is not unlike quitting nicotine in some ways. It is arguable which is the most addictive, in the sense of habituation. The great thing about quitting smoking, which you are echoing, is that from time-to-time you might feel like a cigarette
you don't want to go back to being a nicotine addict. Sounds like you, having found freedom, don't want to go back to being a "sugarholic".. . . . . so keep your resolve and enjoy your new lifestyle :-)
