My first labour was spontaneous. I was given gas to start followed by pethidine. For me I didn't see a difference in the pain. It was the same I was just too spaced out to know what was really happening.

The gas alone made me hyperventilate. By the time I had the peth I was over having to hold the tube in my mouth.

Not sure if it was the gas, the mixture with peth, the hyperventilation or all that along with pure exhaustion, but I passed out 3 times between contractions.

I was offered gas with DD2. I took about 2 breaths on it & my mouth/face started to tingle, so I didn't touch it again.

I didn't have it in my last 2 labours.
