I mainly used Apple Cinnamon flavored rice cakes with various types of full-sugar jelly on top for the majority. A little oatmeal the morning of weigh-in and a baked potatoe after with rice cakes and jelly in between. The morning of, I went to Ihop and had four buttermilk pancakes with blueberries, whipped cream, and LOTS of syrup but nothing to drink. The rest of the day of the show, I used rice cakes with jelly, frozen peaches, a baked potatoe after prejudging, and some peanut m&m's before going onstage at the night show while keeping water to as close to zero as possible. The day of, I didn't eat a specific amount of carbs, I just ate them when I felt like I could be fuller. Overall, for my carb up I just stuck with rice cakes and jelly since I had been using rice cakes successfully in my diet prior to that and knew how my body reacted to them. I'm not sure if this helps any but Good Luck with your show!
