Feel Like I'm on Death Row

This surgery has me feeling like I am on death row.  The whole concept of "no eating or drinking after midnight" is killing me.  First of all, I work until 1030p-1130p most nights.  Therefore, I'm usually eating once I arrive home.  I had planned to grab something nice to eat to hold me over until after the procedure.  Last night I had to rush home and wolf down some food.  I hope I have enough in my system to get me past the time of this surgery.
