Like most things, if you can get through the initial couple of weeks, it becomes habit. You get on a routine, eat the same things, and it really works. But once you splurge and break that cadence, and realize that food can taste good and beer really is proof that God loves us, it is so hard to get back on track. And it's just like starting those first two weeks all over again.
