you can do it!!Keep your eye on the prize!!! It always amazes me how different doctors require different pre op diets! All I had was "I need you to lose as much as you can prior to surgery since it shrinks your liver and makes surgery easier. Avoid starches and sugars" and then 4 days prior, no salad, no red meat. The day before I was on a liquid diet...that's all! Glad I didn't have to do optifast but you can do it!! Have faith in yourself!!! xoxo
