I had a nerve block for my hand surgery as didn't want GA.
I had a broken metacarpal and needed a screw putting in to fix it. They gave me several injections under my arm and around my collarbone and my whole arm from shoulder down went completely numb.
I did have to have an IV for antibiotics and just in case they needed to convert to a GA mid surgery.
I had screens up so couldn't see them doing anything though the surgeon did let me have a peek once the screw was in at it holding the bones together which was interesting.
Immediately after surgery I was taken back to a room to get dressed which was a bit difficult as my arm was completely numb and unresponsive, just like a heavy, floppy useless bit of meat attached to my shoulder. Then they put a sling on and I walked out to the taxi rank and went home. I was on my sofa within 45 minutes of surgery finishing, started to regain feeling and movement in my arm about 3 hours later, which is when the pain set in and I started on alternating paracetamol and ibuprofen every 2 hours.
The surgeon was very matter of fact and 'get on with it' about everything. I remember asking mid surgery when I should be good to work again, bearing in mind this was my dominant hand, which had been cut open, screwed, put in a cast and eventually a massive foam sling. Her response was 'why can't you go in tomorrow?'.
I was really happy I chose a nerve block as did not want a GA and did not want to be in hospital even a second longer than necessary. You do have to really think about how you would react to it though, you can hear them using power tools, cutting, describing your innards and discussing the best approach. If you would find that distressing then you need to consider a GA.
I had previously had eye surgery which was fairly long and done while awake, that involved key hole surgery on my eye and laser, I was given a sedative which was just the standard approach. I really loved the sedative, I have honestly never felt so calm and at peace as I did during that surgery, and again afterwards I stayed half an hour for the sedative to wear off then got dressed and got a taxi home. A bit more difficult that time as I'd had a vitrectomy which required me to keep my nose parallel to the ground for 3 days solid so had to walk to the taxi rank bent at the waist 90 degrees and looking at the floor. Must have looked like a right weirdo!
