For the vitamins- just wait to take any supplements because most surgeons actually say to stop taking all supplements before surgery. See what your surgeon says at your pre-op appointment :)
I’d just add to the list some sort of water bottle with a straw, or a camelback

Good luck! :)
I use this beast coming in at 100 fluid oz. I originally got it for backpacking and SCUBA diving (yeah all that compressed cold air makes you THIRSTY under water.... and it isn't as hard to drink as you think). Now i just throw that massive bladder into my work backpack and i've got water that'll last me all day.
I carry a Camelbak. Seriously, these things are great. You can get them with their own backpacks, or just put them in a regular backpack. https://www.amazon.com/CamelBak-Crux-Reservoir-Set-Blue/dp/B01LA5FCJ2/ref=sr_1_15?dchild=1&keywords=camelbak&qid=1597385561&sr=8-15
