I had an epidural after 48 hours of labour which was a thing of beauty, they have no hallucinatory effects as they’re just local anaesthetic delivered straight into your spine. I napped with mine for several hours. Then I had gas and air when they had to try and manually turn the baby who was “stargazing” (basically fisting me then moving their arm like a mechanical mixer, thought still gives me chills). And then again during ventouse. And then had gas and air again during forceps, the epidural had just been topped up (by me) but it wasn’t sufficient (normally you’d be given a spinal) so I had almost continuous gas and air (instead of having a break between contractions) and did hallucinate with that, I thought my husband was talking to me like I was our dog, then I thought I was dying as I blacked out and saw a light at the end of a tunnel.
Then I had a spinal during emergency caesarean after 51 hours of labour, and diamorphine afterwards. No issues with the diamorphine, the spinal made me very nauseous and shaky about ten minutes after delivery for about half an hour which was a real real shame as I felt so awful I couldn’t even hold my baby, DH had to take him. I do regret that but apparently it’s a fairly common reaction to the anaesthesia.
I also had to ask for pain relief as I’d put on my birth plan I didn’t want to be offered it and my very diligent newly qualified midwife stuck to that! It was only when I saw the gas and air hanging on the wall I remembered it existed - 48 hours in labour isn’t great for mental faculties…
Then after the birth if anything I was insufficiently medicated as despite having a category 1 caesarean, they weaned me off the dihydrocodeine after just 3 days so I was unable to even nurse DS without searing 9/10 level pain at the incision. I had to get readmitted and prescribed it again it was so bad.
It’s tricky, as I think if more women chose to have, and had access to, the most modern epidurals (where you can walk and go to the toilet and top it up yourself, like I had) then actually people would avoid more mind-altering drugs like gas and air and pethidine. But there is so much pressure on women to avoid them that most women see them as a last resort.
