Yeah we like to poison the whole world! lol. I don't think they're bad if one has the discipline to just go once a week like you said.

Oh I'm the same way with sweets, I have a huge problem with that so what we do is have a couple of cheat days every two weeks where we eat anything we want. We found that since we go that long without sweets we usually don't go too wild on those two days, so it works.

Of course purists think it's a horrible idea but I think you can eat what you want if it's only every two weeks. If we feel like something sweet during that two week period we just make something at home and substitute a sugar alternative like Stevia in the recipe.
