Well, you have someone that definitely understands...me
When we travel, it is rough for me, too. Because we are on "vacation," I let myself go and believe that the only way to enjoy it is to relax where food is concerned....like you, I have had to come home and face music that wasn't so pretty...several times. We are taking our kiddos for a week in December to Disneyworld, and I am already feeling anxious about it. The truth is, you don't eat like you do when you are at home, and many times can't! My plan is to lose a few before vacation...so that if I do go up, I will hopefully be where I am ok at rather than having gained.
I still believe we need to be mindful about the choices we make while we are away, but I don't intend to fret about that ice cream cone with my family on the beach...or whatever. Feeling resentful isn't good either...can lead to really poor choices. That wonderful "happy medium..." is tough to find sometimes!
Hang in there...getting on the right track now that your home is truly what counts
