Kiva Dancer, you're so much more diplomatic than I am, but what you say in a tactful way, is what I meant for someone who is serious. But I do believe that substituting sugary foods for sweet tasting other foods is hardly likely to work as well as completely giving up sugary foods.
Yes, feline01, I understand what addictions are; many years ago I was a heavy smoker who kept 'trying' to give it up. Eventually I stopped, but I also realise that we're all different. I used to love fat, and would always spread thick margarine plus peanut butter on my toast. Now the thought of eating margarine makes me want to gag.
