General anesthesia

RaeRae
Sooooo, I'm absolutely petrified of my surgery I have on May 5th. I'm 22 and from what Doc's say, I'm healthy. It's a pretty extensive procedure and I've never been put under general anesthesia before. Never even had twilight sedation when I had a Wisdom tooth removed. Can anyone give me some info about how it feels to be put under and what to expect coming out of it? I'm only worried about this aspect of it. So anything at this point would be helpful.
