Gas and Air was really awful for me.
First time round, I had no idea what labor felt like so let the midwife guide me.
Pain took my by surprise not because of the intensity but because of the sheer surprise with every wave of contraction.
So I just took the G&A as contractions came thinking the pain would be too excruciating to bear.
Have a very blurry memory of the few hours I was on it.
Why would anyone want to feel stoned when delivering a baby is beyond me. And also of course the fact that you have no memory of what goes on at that time. I WANT to remember those precious moments and I can't. All I remember is the midwife shoving it in my face and then feeling spaced out.
After a few hours contractions stopped for a bit and I refused to take anymore.
Had a mobile epi in the end as they put me on a drip to accelerate contractions. Brilliant stuff if you get the right dosage. You are totally conscious, you completely feel each contraction but as a sharp tightening without the pain and it wears off enough in the end that you can totally push.
Downside is you can't walk for the first couple of hours after the shot. You can however be mobile on the bed and be helped into crouching squatting with DH or midwife & pillows to support you.
Second time round I went without. I knew what was to come.The contractions lasted all day and went to yoga, flower market, played with DS, had a long warm bath. The distraction of doing pleasurable activities was enough to take my mind off it really. Only really felt pain about 3 hours before baby popped out, at which point we went to the labor ward. Just about soon enough!
I can not recommend enough pregnancy yoga, breathing and visualization techniques.
Because I had such a blurry memory of the first delivery, I was really looking forward to it second time round rather than fearing it and it made such a difference.
Also, stay at home and have someone pamper you (massage, cup of tea, bath) as long as you can.
Finally be prepared to surrender and trust your midwife/Doctor to make the right decision if things don't go according to plan.
All that matters in the end is that the baby finds his way out safely.
Good luck
