You could try these- Peanut-Butter Cups substituting a trans-fat free margarine (I like Smart Balance) and leaving out the cream. They'd be more bitter, but you're probably used to that having to eat dark chocolate.

Or just try melting unsweetened chocolate with splenda and freezing it. Or have some berries.

Sorry, I read you also can't have soy, so you're probably going nuts. What about jell-o? Or there's a recipe on here for gummy worms made out of jell-o?

Hope you start feeling better soon!
