Is that necessary?
I have a serious sweet tooth too and I have learned to limit it (most of the time - when stressed or at holidays all bets are off, and it does take a little while to "reboot".) I don't think a weird 10-day diet gets you off sugar. You get off it by examining why and when you want it, finding other acceptable substitutes, changing habits and behaviours, learning to indulge reasonably, etc. (in my opinion.) It is going to be a lifelong process and not something that can be fixed in 10 days.
