I had to have slimfast. I froze it and would have 2 teaspoons and be full, by day 3 I could eat a whole one! I then just drank slimfast or canned soup, ice pops n water. By day 7 I ate 2 cubes of chocolate bliss, but didn't want any more! If you feel you can eat lumps earlier just make sure you chew chew chew!
