My patient packet basically says that if I don't stick to the pre op diet, my surgery may be rescheduled or canceled. That's my motivation right there. For me, it's all about motivation. If it's up to me, I fail. Under threat of no surgery, --or in the post op situation, illness-- I'm all over it. I think you will do fine knowing that it's just what has to be done. You may surprise yourself! Just go ahead and see what you're capable of!!
