I've had 5 surgeries, but only put under for 2 (the 3 sections I was awake for). I had two very different experiences with the 2 generals, because they were MUCH different surgeries.
When I woke up from my hysterectomy, I was just immediately in an incredible amount of pain, and I was miserable, and irate. I did not react well at all. When you have a hysterectomy, they generally give an epidural and you're awake for it, or they give a general and you're out. My doc chose a general, which is the more popular method. Well it was serious abdominal surgery, I have a vertical scar from my navel down. That hurts

So apparently I was throwing stuff and hitting people (I don't remember this). A truly extreme, horrific reaction. They had given me the highest dose of pain meds they could give me, so they brought the anesthesiologist back in and they gave me an epidural in the recovery room so that I wouldn't feel the pain for the first 24 hours or so. It was an immediate relief, and I was fine from there on out. It really was an extreme reaction to an extreme surgery, though.
My funny story from the kidney stone surgery I had, though, was that I woke up and felt fine. Which was nice. The nurse kept saying, "Oh look at you, you're doing so well!" But my funny side effect I had from the anesthesia this time was that they had put a stent in my ureter and it hurt/made it feel like I had to pee. And I KEPT repeating myself. "Oh, I feel so much better, but I have to pee. Can I pee?" And then the nurse would say, "If you really have to, I can get you a bedpan, but if you can wait till you get back up to your room you could use the restroom." And then I would say, "Oh, okay, I can wait then." And then we'd go through the whole thing OVER AND OVER. By the time I realized that something felt familiar about it, and I said, "Oh wait. I already asked you that, didn't I?" She said "Honey, you've asked me half a dozen times."

and then I realized she was right. I've seen people on TV have memory issues after a surgery but I thought it was just drama, apparently it really happens LOL. I was fine after an hour though.
