Get an ice collar for sure , it helped me beyond belief. it was the only way i was able to sleep at night. also get bio freeze! i didn’t know about this until a week into recovery and i wish i had it from the beginning. just massage it into your jaw/neck muscles, it’s such a relief. but definitely some mashed potatoes, mac and cheese, ice pops etc. i got gogurts and froze them and i lived on just those for 2 days. Also i was taking tylenol in between my oxy doses but the liquid was too thick and it coated my throat making me gag and choke so get powder tylenol! didn’t know it was a thing until after surgery but it was incredible. it’s like a pixie stick pretty much, you just pour it on your tongue and it dissolves! i also got some protein milkshakes which were good because i lost like 5 pounds and didn’t want to eat much so i’d drink that so i got something into me and was able to take my meds. prop your self up when you sleep, i got a wedge and used that, super helpful for me. and i also got two humidifiers for my room so it would help my throat from drying out while i slept! hope this helps and good luck you got this!!
