In our quest to have our cake--and eat it, too--we've turned to low-cal artificial sweeteners, like aspartame (i.e., NutraSweet and Equal) and saccharin (Sweet 'n Low). The solution is not without danger: Several animal studies have suggested that saccharin, for one, may cause cancer in humans
Stevia--This is what I use. A little costly (50 packs/$6-$7), but worth the cost and health benefits. I don't use it on a regular basis so it lasts a long time.
