You don't have to avoid paracetamol (acetaminophen) if you drink alcohol. You do need to avoid excess alcohol. The only NSAID you can get here without prescription (if you discount aspirin) is ibuprofen. I've been banned from all of them for life due to the threat to my kidneys. I had a terrible time with Tramadol a few years ago, an experience I've recounted here before, but who am I to advise?   I don't think that these generalised internet forums are the best place to be doling out medical advice. I speak as a long-term chronic pain victim. But I can keep moving, and a good psychological boost is to tell myself that I'm a damn sight luckier than millions of other people of my age round the world.
