Challah = nonstop bread eating

Yesterday I made a loaf of challah for the first time from my trusted recipe source, smittenkitchen.com. And it turned out very tasty. Just a little sweet, moist, and tender. I've never actually eaten challah before, so I'm no expert on what it should be like, but it is damn tasty.
I halved the recipe, substituted 1/4 of the flour for whole wheat flour and threw in a few spoonfuls of vital wheat gluten. I feel too guilty making bread with 100% white, though I admit, that fraction of whole wheat flour by no means renders it "healthy." Also, instead of using 2 eggs and 1 yolk, I substituted about a teaspoon of butter for the extra yolk. It's a pretty insignificant amount, but butter makes everything better, right?
Anyways, I didn't braid it, having very little counter space here, but I did do the egg wash. Usually I consider that kind of thing frivolous and ignore it, but I have no regrets about this as it came out of the oven so pretty.
I've been basically stuffing my face with this bread at every opportunity: Some for breakfast, some while studying, some around lunchtime, some more while studying, a slice before the gym, a slice after the gym, and a slice while studying some more. Geez. I really ate a lot of bread today. I'm cutting myself off for the rest of the evening.
I'd offer a picture, but now there is less than a quarter of the original loaf left. My roommate sheepishly admitted to cutting off a slice this morning. I usually strongly encourage sharing, since more carbs for other people means less for me, and plus, it means other people like your baking, but this time I felt slightly begrudging about sharing.
Conclusion: studying with a kitchen nearby is bad news. Especially when there's a fresh loaf of bread sitting in there. But! Challah is good stuff.
