I've had many. Nothing to worry about, really. You'll sleep great, and wake up not realizing what even happened. Most times I've been talking to the nurse, then I'll blink a couple times and someone is waking me up. When I had my elbow done, I asked the nurse when we were going to get started and she said, "honey, you're finished."
Now recovery, that may be a little uncomfortable. This sounds cliché, but you really do need to "stay ahead of the pain" with the meds at first. If you delay in taking what they give you, or try to tough it out, once the pain sets in it's hard to catch back up. That was my experience, anyway. You've got the idea though - lay back for those couple of days, take the meds, and enjoy the nonsexual version of Netflix and chill.
eta: I just realized you posted this last night. Hope everything went okay.
