Vacation

I've been doing fairly well on my weight loss goals this past month and am just starting to finally see some results. I'm afraid my vacation next week is going to completely derail me. My resort has a gym and I'll hopefully be taking some walks on the beach, but I'm afraid vacation eating will get the best of me and I'll wind up right back where I started. I don't want eating stresses to ruin my good time, but I also don't want to come back and have gained back all the weight I've lost plus some!

What's a girl to do!
