I HATE the taste of regular coke. Diet coke tastes like a gift from Zeus.
(Diet coke wasn't supposed to be a no calorie version of coca cola. It was formulated as a diet soda with a completely different taste. That's why they have coke zero, the diet coca cola. People choose diet coke for the taste usually, not as a diet alternative to regular.)
While yes, aspartame is not good for you, your body can not break down non sugars and confuse them with sugars. Our taste buds may be fooled, but our body can not use the chemicals and energy of fake sugars like sugars. In order to use food, your body breaks it up into simple chemicals and nutrients, and it is exchanged through the wall of the intestines, into the blood stream and then delivered on a cellular level. Aspartame is broken down, but since it isn't sugar, it can't be used as sugar. It's a chemical process, you can't "trick" the body like that. The body knows it isn't something to be used and stored and filters it out. But, because it is an unnatural product, it can adversely affect the liver and kidneys which process and rid our blood of waste.
