Denise,
You really have to be ready and in the right mindset to do it. Honestly, if you're not in that mindset yet, it's best not to start (you'll just get frustrated and mad at yourself - for no real reason). If you think you might be able to do it, there's a few things you can do to make it "easier."
1. MAKE THE SOUPS AHEAD OF TIME. Because I'm not a protein drink person (I'd rather drink acid

), I made 3 batches of soup. By having 3, there was enough variety that I didn't get bored. Yes, I had a lot of leftovers, but that's o.k. (you may need it in a pinch on day 3,4 or 5 - I waited too long once and was starving. A 1/2 cup of soup did the trick to keep me from grabbing something horrid.)
2. KEEP SF PUDDING AND JELLO ON HAND. When the carb monster attackes, you need ot have it in your mind that you'll grab a SF pudding or jello. Personally, jello doesn't do much forme - but I was surprised by how much the pudding satisfied me.
3. GET A BIG TUMBLER FOR WATER. Fill it up with ice water and keep it on hand at all times.
4. SHOP IN ADVANCE FOR DAY 3,4,5 - The last thing you want to do is go to the grocery store when you're fighting the carb monster.
5. PSYCH YOURSELF UP FOR A FEW DAYS BEFORE - If you're not in the right mindset, give yourself a few days (play a day and know you're going to start then). Get ready, get set.....wait for it........GO!
