Another bad weekend

Over the weekend, I did not log my foods. And when I stepped on the scale this morning, I could totally tell. Sure, I'm weighing in at 5:30 am after not really sleeping very well, but in the course of 3 days I gained 7 lbs. I ate chips (so my sodium intake is really high) and didn't eat many veggies. I don't feel great at all. You think I would learn my lesson - that eating late at night usually means that I don't sleep well and I end up with a stomach ache. I'm going to do well this coming week and then I'm on vacation. So I'm going to do well for the next 5 days and then try to have moderate days away from home.
