I was on tramadol, paracetamol and diclofenac in hospital. When I came home I tried co-codamol but it really made me sick, so after a couple of weeks I dropped it and just took paracetamol and diclo. Because diclofenac is really, really bad for you (according to my GP) I also had to take omeprazole to protect the tummy, but I only took half the prescribed dose of diclo and dropped it at 8 weeks.
I just take the occasional paracetamol or ibuprofen now.
However, in hospital, there were a couple of very commanding older ladies (in their eighties) having their second knees done, and they refused absolutely everything except paracetamol and even argued over that, and they've both made brilliant recoveries! So if you are as tough as them, Jo, good for you!
To be honest, if you can manage with minimum drugs, go for it. It's got to be better for you - as long as you don't suffer unnecessary pain.
