Aspartame, one of the most common artificial sweeteners found in diet drinks, has been accused of a long list of side effects. Headaches, abdominal pain, fatigue and change in heart rate are some of the reactions associated with consuming aspartame. There are some diet drinks that contain alternative sweeteners, so you can still enjoy a low or calorie free soda if you're trying to avoid aspartame.
