Yeah. I never used to drink diet soda, and I never had a sweet tooth. I started drinking diet pepsi like 10 years ago, and now I crave sweets more than salty snax. I've read all the studies that suggest that diet soda drinkers actually gain more weight than those that drink regular soda in moderation. The theory being, your body gets the taste of sugar, and expects the calories, and when it doesn't get them, makes you crave more and more. I'm addicted, I need to cut out the diet sodas but it's hard!
