Nitrous oxide (gas & air) makes me vomit uncontrollably, even in tiny doses. So it's about the only thing in my birth plan - i.e. please don't administer it AT ALL.
What options does that leave me? No drug-based pain relief at all; epidural; full anaesthesia? Anything else? I'm not particularly keen on any of the options and wonder if they could just find some other method of delivery - Ocado perhaps...
