for painkillers
take a combination of tramadol, ibuprofen and codeine and you are not going to feel a thing for 4 hours solid. i got prescriptions of tramal for when i broke my foot, take one with two panadeine forte (paracetamol + codeine) and then just go to a chemist and get strait ibuprofen tablets (very cheap) and take two. make sure you've had a bit to eat, or the ibuprofen will upset your stomach. the combination of codeine and tramadol in your brain will pretty much flatten you, and the ibuprofen will kill a lot of the pain.
a few things to be careful of: too much paracetamol will kill you, make sure you look at what you're taking to ensure you wake up with a liver; too much ibuprofen will simply make you spew, a waste of expensive drugs, and not fun; codeine and tramal are addictive.
