Fortunately, I don't have any really serious physical problems like yours, but your description of the problem sounds a lot like a friend from many years ago who wanted his lower jaw extended to change the shape of his face. After the first operation, his jaws were wired together. His diet consisted of anything he could run through a blender and sip through a straw. That solution at least allowed for a variety of tastes and a rounded diet for keeping him healthy. A liquid steak followed by liquid potatoes sure sounds like it would suck, though.
