Seeing that you're 5'8" and trying to stick to 1500 calories, that's making me reconsider my 1900 calorie range. Have you been satisfied on 1500? I think I'm starting to sound like I'm fixated on calories but it's the final frontier (lol) that I haven't ventured in my diet.
BTW, I love the fitday log pictures. Very informative! You can look through your journal later and exactly see what you've been eating. Very good job.
Have a good trip too!
