I'm still pre-op but was just speaking w/ my nutritionist today and she's pretty fruity not only about sugar, obviously, but also about sugar alcohols...which I think is what's in Splenda, etc. She pushes for sugar free stuff to have under 9g of sugar alcohols, which seems like it might limit sugar free options. I had never thought, for a minute, that "sugar free" stuff could be on the no-no list.
Good luck figuring out what will work for you!
