Keep in mind that the voice is YOURS, and you're just tempting yourself. I find that if I dwell on something that's bad for me and portray it (to myself) as delicious and desirable, then that voice gets stronger and stronger.
I've read that the key to control is the self-talk we do. For example, I do an 'alternate day' plan of calorie restriction. On M, W, F, I only eat 350 cal for the day. When I began this program 15 months ago, I learned that if I'm tempted by something on one of those low cal days (and I'm hungry!), I just say, "I'll eat X tomorrow," and the desire for that food disappears--really!. And the next day, I don't even think about it (unless it's something I've planned for that day).
In other words, those 'voices' can be controlled if you try.
By the way, I didn't find that eating a little sugar was the way to abstain totally. That's like trying to stop smoking by cutting down.
I just stopped all sugar and artificial sweeteners (when I realized that my body processed them like sugar).
