I had pethadine after the gas made me sick and the epidural wouldn't go into my back. And all that happened was I fell asleep between contractions. It didn't reduce the pain, just made me pass out.
:yeahthat: I had gas & peth with DD1. Did nothing for the pain, but I passed out 3 times... once in the bath! Hyperventilating on the gas probably didn't help there!
