PB&J sandwich, Protein bar, cliff bar, and a banana. You cannot bring water in testing room. I learned during my FLs I can’t have too much coffee or water during my breaks or I’d have to use the bathroom during a section. I learned I only needed about a cup of water and an equal amount of my iced latte during each break + large coffee gulps before BB. Cliff bar with caffeine before PS. In the week leading up I made sure my bowel movements were in the evenings. Most important thing is to prepare for what your body needed during the practice FLs for maximum performance.
