I've had the Carb Smart 1/2 gallons. Tired Vanilla and Chocolate and I'm HOOKED on the vanilla. GOOD stuff (chocolate is good too but I prefer the vanilla personally). I had to stop eating it though. If I remember correctly it's pretty low in SA's compared to like an Atkins bar. But my problem was it was TOO good and I started craving and such. 1/2 cup of something heavenly is not much! I'm saving it for holidays and maintenance only.
