I had pethedine during labour with Dc1 and I didn't like it at all, made me feel sick and disorientated. I've had diamorphine as pain relief for other reasons in hospital and it was great, still felt very in control and calm. I know in Scotland they give you diamorphine in childbirth and where I live (UK) they are doing a 'blind trial' so you will get one or the other but have no choice... so far the midwife told me 80% prefer the diamorphine. I would really like to know I could have this as a back-up (am hoping not to need it!) can I request it if I go to my obstretrician beforehand?
