Pre Vacation Anxiety...in a new and exciting form

Off to Mexico in 2 days - can't wait to spend some time with my husband sans children - and just be an adult.  Oh, maybe I should rewrite that last sentence.... and just be a normal, not HUGE adult at the beach with my husband ;)  I would normally be anxiety-ridden right now, worrying about how much weight I would gain eating and drinking my heart out.  But nope, with my friend the band, I don't really have to worry about eating myself into a hole.  That's all worked out.  I am however pretty worked up about what it will feel like in my new body, in my new bathing suit.  OMG.  I really truly cannot wait to feel normal and average and not large and sweaty and uncomfortable.  Is it even possible?
