I'm on Day 5 of Whole30. I have mostly felt absolutely horrible the whole time. I have stuck with it, though, and hope that soon I will adjust to the lack of my usual horrifyingly bad food choices. Other than the fact that I generally feel sick or have a pounding headache, it has not been too hard. I have been using recipes from Whole Family Strong, and on the first, I made Apple Bumbkin without the maple syrup, of course. The texture takes a little getting used to, but it tastes great. It's a good thing I like it, because Troy does not, and I have been stuck trying to polish off a 9x13 pan of it by myself. I've eaten two large servings a day, and I'm down to just one serving. I probably won't ever make this again, because it's just no fun having to eat the same thing five days in a row.
I would like to nominate myself for some kind of medal, though, because my 10yods has a sheet of Pillsbury Croissants in the oven right now, and I guarantee you that I won't eat a crumb.
