Like you, I am definitely a planner. I made sure to try all the premier protein shakes, buy enough of everything to get me through my first two weeks post op (I'm 1 week post currently) and my words of advice are simple. Don't spend a lot of money. Everything I liked prior to surgery, I am struggling with post. Nothing tastes the same and it was days before that changed, but even more so - I suddenly can't tolerate anything cold or even room temperature. So, the only thing working for me in homemade bone broth soup. I can sip and it doesn't bother me and sit in me like a brick. Popsicles are just now becoming a friend and jello is squish around in my mouth until it becomes warm liquid.
Try things, but don't go overboard in the purchasing. - I read someone's post that said similar but I didn't listen. Oh how I wish I did. The good news is that most of the stuff has a long shelf life, so it will be there as I go through many of my new stages with food reintroduction.
