Drugs - yes, gas then the epidural.
Complications - well yes but my baby was presenting as posterior so I don't think they were due to the drugs. It was a long labour and had to have the drip to make the contractions more regular and they said it might also help turn the baby which it did. No other complications. i was worried I might not be able to push but the MW guided me through and didn't need any instruments to help deliver
Feelings - I was exhausted and probably in shock after the birth. I think this was due to the labour being 25 hours and not having had sleep, food and the pushing part took about 2 hours. I was disappointed that I didn't have the post-birth endorphins.

I don't regret my choice to have the epidural particularly as the labour was long and I had wondered if my baby would turn and if it didn't then I thought I might need a c-section as this happened to a friend of mine. I also ripped and had an episiotomy and I didn't feel it as they stitched me back up.
