I'm the same. I never was one for sugar, in fact, there's a great line in the movie Snatch:

Whenever I'm asked if I'd like something sweet or sugar for my coffee, that's my line. "No thanks, I'm sweet enough."

With Lily it's the same. She's allowed one sweet a day, and I try to give her most things unsweetened. There are some exceptions, of course, like Ketchup which we both enjoy. But since I prepare most of our food myself, it's actually easy to stick to low-sugar.
