What do you do to replace the craving?

I’m lessening my sugar intake, but find I get genuinely kind of ‘huffy’ like a kid when I don’t get to have sugar in my day. It’s the evening now, and I just had a low sugar old people biscuit to curb the upset, but I still feel ‘incomplete’ kind of in my stomach and mind.

When you feel the compulsion to have something sweet, how do you overcome it? I find it doesn’t even subside if I distract myself, as it seems to return even after this too!

Is it just a plain old addiction situation?
