I'm definitely exhausted too... I'm getting a band the same day you are, Ana... been doing the liquids since 3/30. My doctor lets us have 2 cups of water-based veggies (like, not potatoes or corn) and as much broth as we want.
I have been making soup for dinner out of these things... I take 2 cans of chicken broth and boil some chopped carrots, onion, and celery in it. Grind a litte black pepper over the top, and that's dinner.
Definitely helps me sleep at night.
