Haha, we purchased some lovely treats, lots of chocs, gingers, marzipan, etc, not forgetting some special booze. We have no kids though and are spending this xmas just the two of us, so perhaps easier to control what come into the house..
That said i am a chocolate nibbler and would literally graze them ALL away before xmas if i didnt have a handy glass linen cabinet with a key. So i got DP to lock the fucker and hide the key, or i would have to re-purchase the chocolate collection and whiskey all over again.
It is a good idea if you can vouch that the key will not be handed over to you if you stamp your feet 
Other than that, there is no reason to go mad, every day, over the entire period. It is a lovely time to put feet up and self indulge, but if you are concerned about self control, i can see this would be a very difficult temptation to avoid. We tend not to perceive xmas a a time to restrict, it is emotional as well as traditional!
My advice would be to keep the indulgence to xmas day and boxing day only, then again at NY. And don't eat for the sake of it, either. I don't have to watch weight but i do get hideous IBS if i go crazy, especially with seasonal veg/sugar.
