Lord, have mercy! I pray you'll have victory over this area of your life! Look upon it as an exciting challenge of sorts! Gradually cut out the sweets and sodas and before you know it, those sweets will taste sickeningly, cloyingly sweet and you'll barely be able to stomach them! I started to use the natural stevia powder for sweetening my beverages. It's quite expensive, but I tell myself, "This is it", and try to "award" myself a package of stevia in my tea every once in awhile as a treat. And, as Myrrh said, chose to enjoy fresh fruits and vegetables over starchy desserts. Avoid artificial sweeteners like aspartame-it's terribly dangerous and a known carcinogen. It's worrisome how they manage to sneak it into so many products, including nearly all chewing gums. Every time you have a craving for a soda etc. tell yourself it is not a soda, but pure chemicals, dyes and sugar. If you are tempted to buy junkfood, consider nuts and dried fruits, if you don't have any allergies to nuts.
Okay. End of sermon.
