Good Luck Susanne! In just a few short days you will join the "losing" side. Remember to keep good thoughts and breathe deep -- it really helps. Like you, I was addicted to my diet sodas, Diet Coke to be exact. The dietian told me to get off them early so I wouldn't have a caffine headache after the surgery. When I told my surgeon's nurse, she laughed and asked why, since you are on pain meds after the surgery.
