In short it was amazing. After my first labour being horrendous with a failed epidural, being pinned to the bed and 48hrs of pain I was dreading labour. I laboured for 6 hrs at home on my birthball with no pain relief, went the hosp was 4-5cm and started g&a which was amazing given that I progressed to 10cm in an hour. It helped me focus my breathing whilst taking the edge of the pain. It didn't take it away completely but being honest I wouldn't want that as I found I needed some to understand what my body was doing. I felt my baby drop and engage, I felt her drop in to the birth canal and I felt my body push. To be honest it was a bit surreal but utterly amazing to experience and I don't think I'd have been able to do it without a bit of gas and air...
Good luck for when the time comes as hard as it is try to make the most of every moment.
