Get out of town, lose a pound

My mom and I both lost 6 pounds on our Mexican vacation. Now, part of that is probably due to the fact that we both had Montezuma's revenge and couldn't keep anything down for 24 hours after we got back. But maybe I could market myself as some sort of vacation guide/diet guru. I can see it now: "Go on vacation and come back thinner, tanner and poorer than when you left!" Look for me coming soon on QVC.
