You can always give it a try and see how it works. Some people can take AS outside of reward meals, some can only with protien, and some can't at all. You'll have to eb the one who decides.

Rememebr to people switching from Atkins to CAD sometimes gain a little weight initially as your body readjusts to the extra carbs. This is usually gone after a bit. If you gain at first, or don't lose for a bit, don't get discouraged. It could just be from the diet change, not the splenda or that the plan isn't working for you.
