have you heard of
percocet????Oxycodone is the opiate in percocet.At 200mgs of
methadone you won't benifit at all from taking all of those
oxycodone at once.When you get on a steady dose of methadone and reach 80-120mgs a day you then are at a opiate blocking level.You should raise your methadone and try and come off the
fentanyl as it is a very hard drug on ones mind.I wouldn't even bother with the oxycodone because you won't even feel them at that high of a blocking dose of methadone.I was at 400 mgs of methadone and I took 1,000mgs of
morphine all at once and it didn't do a thing.I'm now at 300mgs a day and it still blocks all opiates.That's why I thought it would be good for you to raise your methadone as all the other opiates won't work very well.....Dave
