The best thing is when you discover a food that you really enjoy that is great for you, and it no longer feels like a chore to be "clean". I eat spinach, broccoli, and squash for meals/snacks because they taste so great.  Try more "clean" foods and drinks (I actually found I don't mind drinking Coke Zero instead of Coke regular) and mess around with it.  Then, start getting into an exercising routine and you'll love the way it feels, and hate it if you miss a session in your routine. After it all becomes routine, keeping a clean, yet easily happy and comfortable, life is quite attainable.  Congrats on your week, and I hope it has, indeed, changed you for the better!
