I found this interesting article on Aspartame and their side effects. Aspartame-containing product that actually makes you crave carbohydrates and gain weight. The side effects of aspartame poisoning are causing even worse issues for people. If you are having some issues that your doctor and you do not have a clue to the cause, it may be time to try removing the artificial sweetener from your diet, especially diet sodas. There is no nutritional value in drinking these beverages and can be linked to many side affects of aspartame. Try making a healthy switch to water instead of reaching for the sugar free soft drink. This change could bring your health back in balance.
