My wife dreaded the idea of liquid diet, but we prepared it ahead of time. We did Jello jigglers so she could eat it with her fingers, Atkins Protein shakes, and we made some simple Soups (broccoli and cheese, creamy potato) and strained the chunks out.
It doesn't last too long, and when you hit puréed food, the list that you looked at and thought sounded gross or boring, you will be ecstatic for (my wife is over the moon about instant mashed potatoes).
Good luck!
