How to Handle a Vacation

This is what I do:

-search out a restaurant before hand and try to pre-plan or even pre-log food.
-pack a bunch of snacks and things to eat that would hold me over if I get hungry between meals.
-take a cooler, lots of water bottles, even stuff to heat up in a microwave, if I will have that available
-not expect perfection from myself, just control portions and enjoy my trip. Maybe even have goal just to maintain current weight

As long as you don't "throw in the towel", but rather get back in a routine when you return, you are not starting over!

OOps, don't know how I glossed over staying with family. That's a bit tougher. If you're comfortable, I'd share privately that you're watching what you eat. Or else, just be very gentle with portions. I'd still take the snacks on my own, but not food to heat up, as that would feel rude. If you eat out, maybe you could still plan that. Don't sweat it too much. This is life, and the "throwing in the towel" statement still applies! Have fun!
