To anyone using Oxycontin CR (controlled release, same as ER) and you are taking them whole as directed, before you give up on them because of tolerance or the pills are found to not be broken down by your body you need to get some razor blades and cut the pills into thin slivers or slices and eat it like that...you WILL find a difference. This is why I recommend especially if in Australia you buy the Sandoz generics because they crush to a powder....much quicker absorption when taken as a powder. IR oxycodone will jack up your tolerance so try to limit taking them. In addition....to get more out of your ER/CR meds take a little IR dose about 15mins after your oxycontin dose and it works as a great "kicker". Keep in mind all my methods for pill tampering will ultimately jack up your tolerance but it will also mean your prescribed dose won't need increasing for a few more months. Everyone's a bit different but these techniques do work.
