My pre-op diet is all liquids for 2 weeks pre-op. I have to drink 3 protein shakes a day one for each meal and can have sugar free Popsicles and jello. Also broth. I am now on day 5 I can't say it is easy, it is a struggle but not un bearable. I keep going to frig to see what is there but then remember no eating. It is also hard because I have 2 young boys 8 and 10 so I still need to provide for them.
