Oh but there is a maximum dose. It's the amount that you don't wake up from. Oxycontin has killed many people over the past years. I would stop worrying about how much you can take and start thinking about living again without oxy. It is a terrible drug and will take you to a really bad place if you continue to up your dose. I speak from experience. Getting off of this drug was by far the worst experience of entire life. Do yourself a huge favor and stop before it gets any worse. Each day you continue to use it is just that much more time that you will have to answer for later. Good luck in your recovery if that is what your looking for. guv
