Linmed private hospital doctors are great nurses are a problem

I had gallbladder removed. After the surgery I was wheeled back to the post op ward and the surgeon saw me close to 6pm. He said he would get me the staff to give me something for pain that would likely make me sleepy. I also asked for water as I had nothing to drink for 12 hours at this point. The “something for pain” never arrived and I got a water jug at 8pm. They came with the pain injection in the morning after 8am and I was going home at 9am so I refused it ( bet I was charged for it). The nursing staff are plenty but absent. I had no idea what I could do or could not do before someone gave me a reluctant rundown at about 10pm. Took my own sleeping tablets. Cost? Over R36000 for one night plus surgeon plus anethatist.
