Combinations - ms contin and oxycodone capsules

[zazen68]

A few years ago I was hooked on IV use of oxycontin. I eventually found my self in a hole and started taking methadone (60mg daily). but that turned out to be a mistake. It was the worst withdrawals ever when the doc took me off of them because of a black box warning regarding heart problems caused from methadone use. Now Im on 60mg of ms contin 3 times daily, and recently came accross 5 mg oxycodone HCL capsules. Is this similar to oxycontin without the time release stuff? Is it dangerous to IV? what about using the morphine and oxycodone? they are thin little capsules (no apap).

Any thoughts?
