I'm not sure I'm the "tomorrow" source, but I do use that technique all the time. 90% of the time, the next day, I'm over the craving...the other 10% of the time, I usually have a single serving of it and move on (we're on day 3 of "I'll go get frozen yogurt tomorrow", so tonight I may get some. We'll see how I feel later and what the flavors are).
This dovetails nicely with a philosophy that I don't know she's ever stated, but that I associate with Glory87...if you're going to eat it, make it the best/most delicious version you can. Glory would talk about her "off plan" meals...was she getting junk? Nope! She was having a lovely meal out, a glass of wine, and splitting a dessert. Similarly, I AM considering frozen yogurt tonight, but my local shop publishes what nonfat flavors they have that day, and I check the list before I go. If they don't have something that I LOVE (In Fall, this is Pumpkin flavor and it is insanely delicious...The shop I go to also has a Banana flavor that I top with Nilla wafers and fresh blueberries), I save it for another day. That way, when I go, I really enjoy that treat and don't feel like I settled.
