1. Drink three times as much water as you think you need. Just do it; you'll feel better.
2. Any of the following now count as exercise and entitle you to sit down and rest a while after doing them:
a. Unloading the dishwasher
b. Folding and putting away laundry
c. Carrying groceries from car to house
d. Walking one block to put something in mailbox
3. Given strenuous caloric requirements upon your system, it is fine and advisable to buy Oreos and Cheetos and ice cream in one grocery store trip. You need the energy.
4. Start planning now for your birth and post-partum experience. It is important that your whole family be aware of your preferences; namely, who will bring you your first shot of hard alcohol after the delivery, what that alcohol will be, and how it should be served. (Honestly, how unfair is it that we can't drink? Who needs it more than we do??)
