Yay!!!! You ARE awesome and yes, you CAN do this. It IS doable.
I struggle with the nights as well, as do many people I think. Yes, I even plan that

. I try to have something in mind to do every single night. Something to take my focus off of the food. Whether it be cleaning out a dresser drawer, hemming a pair of pants, doing my nails, straightening the house, reading a particular magazine, just SOMETHING (the "Y" is a great idea). I also always have a large cup of hot flavored tea every night.
Thinking it through before we eat is another good habit to implement into your life. Self talk is also vital. We need to constantly remind ourselves of why we're passing up on the so and so and that if hunger isn't the problem, well then, FOOD isn't the answer.
Hang tough, especially in the beginning. Hang tough. Stick to it like glue. Like glue. Remember, it's SO worth it. More then you can imagine. You won't ever regret losing the weight. Not for a teeny, tiny second. In fact, you will wonder why you didn't do it sooner.
