Biotene swabs for dry mouth - after surgery you feel like you will never get your mouth hydrated. Heating pad instead of hot water bottle. A thermal cup because stuff gets warm/cold because it takes awhile to get stuff down after surgery. After the first week, I could barely tolerate sweet protein drinks, I had ready-made Isopure punch or blue raspberry and mixed it half n half with premixed crystal light, Isopure is tart, 4ogr protein for 20oz and clear. Also tea because warm liquid relaxes the muscles in your esophagus and stomach. I agree on the Sam's Choice Bone Broth at Walmart, I added garlic and simmered vegetables in mine for extra flavor then strained it. Audible books for while you are walking. Take naps when you need them, sometimes you don't realize you are tired and BAM! You hit a wall of exhaustion five minutes later.
Good luck.
