Please don't cancel, I went thru one in Dec and really it wasn't bad. My doctor did drug me, and when I asked for more drugs in the middle, he gave me more drugs... so I didn't really feel anything.. He knew I was very nervous and was respectful of that so it worked out. I remember bits and pieces, but nothing that was unpleasant.

Also, afterwards I did sleep alot.. so the time passed pretty quickly. And they keep a close watch on you..
