The hospital and the Suporn clinic gave me three types of painkillers to use at my own discretion - tramadol, idarac and paracetamol.
I tried the tramadol only twice, and while it did what it was intended for it also gave me a strange half-dreamlike sleeplessness at night that was positively wonderful, but I decided that it was clearly messing with my head and stopped using it.
Idarac did nothing for me, so I tried it a few times and then stopped it.
The paracetamol has been strong enough for me all the time, I never needed more than half the allowed daily dosage, and I was completely off any painkillers three weeks after my surgery. There was still a little pain, especially during dilation, but I preferred being able to feel what I was doing so that I could avoid accidentally injuring myself.
