It's really a crapshoot (heh) - some of them have a really strong laxative effect, some don't. I think you just have to experiment because they all have different reactions, and react differently with different people. I've been fine with stuff other people had trouble with and vice versa.

So far tho, I found the Nestle's SF turtles are indistinguishable from the real ones. And Hershey's makes miniature dark chocolates that are really good.

I found some divine German chocolate bars made for diabetics and sweetened with fructose. Anyone know if they are safe? I ate a few squares and had no bad effects, but I worry they really aren't to be trusted on this diet.
