Are you allowed raw veggies? I was and it got me through until the last two days of the liquid diet when i couldn't have them any more. Try those. i also made a dip out of plain Greek yogurt with some dry Ranch mix.
Go to KMart, pick up Smart Sense Lemonade, it will curb your sugar tooth. It's sugar free but in a good way, it tastes just like full sugar lemonade. Hope it helps.
