I recently signed paperwork to get a laproscopic tubal ligation after I have my second kid this July; asking about the procedure at my OB was like pulling teeth without meds, no one wanted to tell me anything, not even when I could sign the paperwork to begin with. I ended up having to pick out a pamphlet on laproscopy and read the paperwork as my main sources of information. Very upsetting for me. (I know there's a reason they don't want you to decide on it until a certain time, baby might pass away, etc, I just wanted to talk, though.)
Though I did laugh out loud when I read, "By signing this you agree and understand that the procedure described means you CANNOT HAVE CHILDREN anymore..."
The only comparative experience has been my mom, who had a laproscopy back in 1991 when my youngest sister was born and they did hers immediately after the birth. My doc says they only do that if I have a C-section at the birth, otherwise it's an in-office thing with minimal anesthestic. I know I'm done after this; various reasons but number one being that I am happy with two kids (or one, should something happen) and do not wish to continue to reproduce. My mom says it's very liberating.
