Hi Jennifer,
Thanks for ordering with us, but i'm going to have to scold you a little here...
ALWAYS call us before you order. We do have promo codes available that we could have provided for you. If you want to call Terry at the 800 number above, tell him your circumstances and he should be able to work out something for you. If he can't get it applied to this order, he can get you a credit for your next order. Let him know i told you to call.
As long as you're not on the full fast now, you'll be fine. If you were on the full now, you might want to go modified for a few days before your vacation so that your stomach adapts to food again. We'd hate to see your whole vacation spent in a tiny room....
As for what to do on your holiday. Try to get all three of your shakes in before lunchtime. Be sensible with your regular meals (lean/green), try to stay away from those naughty foods, and have a shake in the evening. Remember, long as your getting regular, continuous, healthy meals throughout the day, your body will be satisfied and not store your food as fat. One thing NOT to do is eat only 2-3 large meals for the day. This tells the body during those long stretches of not eating that it better start storing fat.
So regular intervals....portion control and slurp your water and you'll be fine. You shouldn't gain a pound and if you're lucky you'll come home lighter than when you left.
Nancy's REALLY tied up right now, but may also be able to address this for you before you leave.
Have a great vacation...
