wait, how are you getting naproxen?

Whenever its prescribed here, its paired with some sort of intestine protection medicine to stop it burning holes in your stomach/intenstines

Ibuprofen is much safer, so long as you eat with it.

Paracetamol is also safer, so long as you don't OD.

BUT! so long as you stay below 4 grams a day, you'll be safe. (yes yes, in some situations you can take double, but unless you are under supervision, thats asking for liver pain.)
