Never take tylenol "like crazy", the max dose of acetominophen is 4000g per day, but better to stick to 3000 if taking for more than a few days.
In the UK you can get cocodamol (paracetamol and codeine) over the counter for lower dosages, but pretty sure that's prescription only in the US, and more likely to lead to dependence.
