I am half way through my two week OPTIFAST diet. I must say it is brutal. Not from hunger pains so much, but from the "side effects". I have not yet cheated... I did try to have a Dora the Explorer ice pop yesterday and my wife somehow overpowered me and took it away and said I could not have it because it had sugar. She's such a dictator. But I am glad she stopped me. I do not plan to cheat, I really want this surgery to go well.
