Yet another bisalp post! Questions about recovery.

Hello! My bisalp is scheduled in January. I'd love to hear if anyone has tips for recovery. What should I make sure I have on hand to make myself comfortable? How many days of food should I prepare in advance (someone will be full time with me the first day but after that I'm mostly on my own). Anything else I should be preparing in advance that I might not be able to do for myself? Thanks a lot y'all!
