Yeah, I have ice cubes galore in the freezer, and soup cans - mushroom, pumpkin, neutral stuff.
I will probably subsist on fluids - protein shakes and soups and the like, for the most part, until I can feel brave enough to chew again.
Got a bag of salt for warm water salt rinses, and well, I think that is about as prepared as I am, as well as the specialist mouthwash they gave me. I'll be fine. Just a journey into the unknown.
