Right, and that's the very reason they're knocking you out of ketosis. You may very well be one of the people who are affected by sugar alcohols. Give them up for a time (or forever) and see for yourself if it makes a difference. I know it's easier said than done, I'm having a hard time right now myself. I'm really proud of you for giving up those things you KNOW you can't handle.

Your body loves you for it and will pay you back in spades!!!
