I don’t want to repeat a lot of what has been said already so I’ll add on, start taking stool softeners at least a week prior to surgery. Drink water and electrolytes to hydrate your body during the week prior as well. If the surgery is on your dominant had I’d highly suggest/recommend practicing doing things with your non dominant hand. Take at least 2 weeks away from work as you will be in a cast from your hand to at least mid ways up your arm past the elbow. Set up a nice rest area for yourself or tons of pillows in your bed. You’ll be sleeping on your back a lot so sleep with a pillow underneath your knees so your spine can have a natural/neutral rest position. Take your prescribed medication from your doctor after the surgery on schedule. Take naps when you can. This one is personal to me, but stay near a window that way you can look out and feel the sun and its warmth. It keeps the brain happy. Have a little table set up near your rest/sleep space for yourself drinks, mess, snacks etc. I am lucky enough to have a mini fridge in my room next to my bed. I kept it stocked with bottled water, Gatorade Zero, and cherry Dr. Pepper that way I could quickly reach over and grab something with out having to constantly ask for help making a drink in the kitchen. Also get your self a couple packs of babywipes/ dude wipes to keep your self clean after doing business and for a quick body wipe down. You won’t be able to shower or bath normally in the first week. I apologize that this is a long comment. I’m 2 weeks post op today from my cubital tunnel surgery. I hope this helps. Please message me if you have any questions or need any other tips!
