Susan,
I don't know how carb sensitive you are, but have you looked into the Zone? The carb count is a minimum of 99 grams a day which a lot of people think is high, but I am also one of those that can't give up my fruit. A Week In The Zone is a perfect starter book that you could check out at the library or buy for $6.99. Just a thought. If what you are doing is working for you, then don't change a thing! Good luck and don't give up!
