I think 64 oz a day is a goal, but you probably won't reach it for a while. Still, try, and ocntinue to push fluids during all waking hours because you don't want to get dehydrated. When you get to where you're able to stay awake, and drink an ounce (about the size of one of those little medicine cups) every 15 minutes, you'd get your 64 oz in 16 hours. Think of it as your only job for now. An ounce every 15 minutes will soon become every 10 minutes, then 5 minutes, and so forth.
Congratulations on your surgery!
