Hi. I had my op on Wednesday 10th July and it was the Monday after before I felt human after the GA. I stopped taking my co-codamol on Friday 12 as I threw up during the night on it and just had paracetamol which I found just as effective as the co-codamol. Paracetamol is stronger on its own than codeine is and 10% of the population to do have the enzyme to convert codeine into morphine – think I’m one of the 10% lol as it just didn’t do me any good. All in all I felt better 1 weekpost-op. hang in there. It will get better x
