I just had gas during Hudsons birth. It made me so off my face it is just not funny, which I wasn't expecting and I actually don't clearly remember a lot of the birth up until they took it away from me lol. I think next time I'd rather try baths and showers for pain relief and see if I can manage with just that as, as bad as the pain was I didn't like the effect of the gas on me, and I think I probably would have coped ok without it.
