No you WON'T feel it. Didn't you just say you've been using 40-80mg of oxy for 2 months? That 1 TIME RELEASE morphine will not even feel like a codiene to you.
I'm not sure if you can break the time release by just chewing the wax off the grains (they're usually encapsulated in a form of wax so just grind it with your teeth for 5mins) but 60mg will most likley not to a thing to you. I don't even think 2 would honestly. If **I** was using 40-80mg of oxy for 2 months, **I** would put 3 of those morphine pills in a mortor and pestle, and grind them down to dust. Than cram all that dust up my ass if I was actually EXPECTING any form of a high from it.
Morphine is much weaker than you think. Orally I've taken up to 300mg with only minimal effects, and that was with almost no tolerance. You HAVE a tolerance, and I'm not trying to kill you, but I doubt 2 will even do anything.
And if you can find a way to break the time release, and plug them, you'll use them much more efficiently.
Good luck and BE SAFE.
edit: Laslty about the whole overdose thing. The only way I think you can OD on morphine is if you haven't taken opiates for a looong time, and straight out took like 500mg-1000mg of it. I'm prob wrong, and I'm sure people have died off lower amounts, but what I'm saying is if you are taken those amounts of oxy, morphine is MUCH weaker.
For me 30mg of oxy feels like around 180mg of morphine.. actually not even cause the morphine still feels weaker.
Don't expect an incredible high at all unless you find a way to plug them. Ok I'm done now.
