Hi there! First of all, I'd like to say that I know the feeling! Although, my biggest problem with sugar/sugar substitutes are through sodas. Through some research, the best option, though a bit more expensive, is to invest in Stevia, which is a natural sweetener?
The book I'm currently using as a 'guide' is Jorge Cruise's The Belly Fat Cure. He suggests to avoid the artificial sweeteners and go with sugar alcohols or Stevia. This is especially relevant for his lifestyle, since the daily allotment of sugar is 15 grams. (Comparing this to a can of soda made me CRYYY!)
Anyway, I really can't answer too much about this program or the product itself, as my mom bought this book this past week and only shared it with me on Friday.
^ However, you can read a bit more on Stevia here!
