more on diet soda

I almost never watch the news.  Since we just moved to the Charleston area, we are trying to get acclimated to the area quicker, so we check out the local news every now and then.  They just aired the "medical" section and said that Americans, on average, drink 57 pounds of diet soda per year!!!!  They questioned whether those who drank it could be addicted to it.  The research they were referencing talked about caloric values and how diet soda "fakes out" your brain and causes cravings.  One woman said she drank 6 cans per day.  10 to 1 says she has big headaches right before her menstrual cycle.
