My scale said the same thing....from traveling as well. I'm trying so hard to put it behind me and move on and not worry about it. However, that is definitely easier said than done
Frustrating to see your hard work that took forever to reach go away so easily!
But, today is a new day and I've been pretty good all day long. Good food choices and I jogged 3.5 miles (with a couple walking breaks thrown in for good measure) at the gym after work. Guzzling the water and hoping that things whittle their way down throughout the week.
