I can totally empathize with the Diet Coke situation. I gave up the stuff too (addict here) and when I first let myself have one again I was disgusted. Diet Rite is much better. I still have Diet Cokes in restaurants occasionally, but ick is aspartame not my sweetener of choice!

Perhaps try Diet Rite? I also indulge in mock danishes. There are great cheesecake recipes on this site. There are sugar free candies but watch out for sugar alcohols and possible sweet cravings.

Good luck kickin the sweet habit!
