It's hard to quit! I have basically stopped because the caffeine keeps me up at night, but about once a week I just crave it and give in.
I've heard that diet sodas are actually as bad, if not worse, than regular sodas because of the effect on insulin in your body. A lot of people get cravings for sugar and carbs when they drink diet sodas. The Weightwatchers program almost encourages drinking diet soda so it can't be detrimental to weight loss, right? The new program even lets you count diet soda as water, right? That seems odd to me, there is no substitution for water, water is so good!
