I would of loved to be able to have broth... I mean check vanilla, chocolate or strawberry flavor gets old... quickly .
7.5/28 days. I am so envious at people who only have two week's from what I saw normally people have 1-2 week and not 2-4 week like my surgeon office does....
It seems a bit different what they do in Canada vs United States. For us, with the free health care the way can be VERY long. I waited two years after seeing my surgeon to have an actual date so I think they just don't want you to take more weight if you do a diet before hand and get heavier after.
If you are scared for the weight I would suggest to start a food journal, it might help you lose a bit more.
I started my pre-op last monday mine last for 4 weeks.
In my doc office it is 4x optifast /day and 1 veggie cup per meal but I haven't been able to take them.
Good luck
