I felt the same way...then once I was done I thought about every food item in the world I should had before the big day. Relax it will be here bfore you know. Make sure you are stocked up on broth, vitamns, protein drinks.
It's completely normal. Just think of it as your rebirthday is the day that it is meant to be. God has blessed that day for your surgery. Now hit your favorite food spots before you have to go on liquids.
