Thoughts on Glucose Goddess' Anti-Spike Formula?

I've looked over her hacks and think they seem solid - at least they align with what my doctor's been telling me to do in the hopes of regaining insulin sensitivity.

With the holidays here I'd like the option of being able to eat more carbs/sugar then I do on a regular basis because there's just so much good food that isn't IR friendly! Have any of you tried Anti-spike and seen any results? Thanks!
