What types of things were you allowed on your pre-op diet to eat and how long is it?

I was allowed sugar free pudding & Jello, protein shakes, broth, juice and all the water I could drink.

Many don't know this but if you buy the sugar free jello that you make on the stove and instead of adding water to it to cool it down drink it while it is hot. This really helped fill me up when broth did not do the job.
