I had 3 of the mini Hershey bars and 2 of the PB cups last night. I figured it was Saturday, if they made me sick, I had time to deal with it! They didn't make my stomach sick at all, like maltitol does. They taste great, hard to stop at a few pieces though. I found mine at the grocery store, I wasn't even looking for them, they had a display and I said "ooooooh, gotta try these!" Yum!
