Question-has anyone not been given the 2 week pre op diet and only given 4 to 7 days that is a lower BMI? My surgery is Tuesday afternoon and I start on all liquids tomorrow. The nurse told me since I am at a lower weight that I didn't need to do the entire 2 weeks because it had to do with the size of my liver. I tried to start yesterday and I have no control. Has anyone HONESTLY not followed the pre-op diet?
