Watching OBEM, some of the women who have pethidine seem really out of it - there was the midwife who said it felt like she was in a club.
With my first, I had a very long labour and about 24hr after waters broke went into hospital to be induced. By this time I was exhausted having not slept for two nights and had to go into labour ward and get hooked up so had an epidural, gas and air didn't have any effect. It was fine for pain relief and meant I could - not sleep - but get some rest. But when I finally was dilated, although I did push for an hour or so, I needed a forceps delivery and episotomy.
Am hoping with my second to try the maternity unit and water birth, as should dilate quicker. But am worried I will need pain relief, and am a bit freaked out by how out of it people seem on pethidine. The epidural relieved the pain but didn't make me feel at all trippy or liek I had to tell my husband I loved him 100 times 
Any positive experiences with pethidine?
