Epidural??

Laughing gas relieves only about 20% of the pain, so it depends on your pain tolerance. Also if you want wait and see whether to take epidural, u'll have to decide fast too. I used laughing gas and only asked for epidural when I couldnt take the pain, by then i couldnt sit upright for 30mins already because the contractions were moee frequent amd getting stronger, so they couldnt give me epidural. Also by then i was already 6cm dilated. I was in an 8-hour labour.
