ok, drugs:
I used gas, looooooooooooooooooooooooooved the gas!

It took the edge off the contractions so I didn't need any further meds, helped me concentrate on breathing, took my mind off the pain, and gave me some nice light feelings! lol! My DH also liked the gas!
I also had a spinal block for a manual removal of the placenta. I was terrified of having a needle in the spine. But it really didn't hurt at all, they were great. The catheter that came with it DID hurt

. The spinal block made everything below the waist numb, and wore off within a couple of hours - no further effects. I had it AFTER my baby was born though, so it didn't affect my birth obviously!
On the placenta syntocin injection. I had it both times as routine. My first birth, no problems, I remember pushing the placenta out, looking at it.
My second birth though, they gave the injection, the placenta didn't come out. They pulled the cord to ease it out, the cord broke. Because I had the injection, my uterus was trying to clamp down - but it couldn't because there was still placenta stuck in there, which just meant I kept bleeding... the placenta had to get out quickly or I would heammorage (sp?) - hence the manual removal. This is not a particularly common occurance, and not meant to scare you, just an explanation of how I came to my current thinking...
If there's a next time I think I'll forego the injection and let nature take it's course...
