My MIL is awesomely taking my husband and me to the gulf coast this weekend. Awesome! Sort of...
I am very grateful for her taking us, make no mistake. However, I just started my mental and physical turn-around from a decade of overeating. My MIL is the kind of person always makes excuses for overeating. "I've had a rough day" "It's the weekend" and yes..."We are on vacation." She also is apt to make comments when someone eats healthy around her that make their choices about her. She is going to insist on paying for dinner, but will also tut-tut when I choose a healthier (and often  more expensive) option. Asking her to stop makes her pout and she feigns hurt feelings. 

Hubs and I are both on board with getting healthier/losing weight. I don't want to think of my vacation as a time to "cheat" because then that makes what I am trying to do every other day a deprivation instead of a my new lifestyle.
<bot>: MIL causes me stress and I don't want to eat my emotions on my vacation. She will try to make me eat like her.
