thats the problem i mentioned above, ever since i been on suboxone, oxycodone/oxymorpone/hydrocodone/hydromorphone doesnt give me any full efects even after 72 hrs after my suboxone dose. just morphine, methadone, and heroin....once u go to suboxone anyway, ur tolerance is jacked, plus the receptor clogging issue too; lortabs and oxys just aint gonna hit the spot...i went 5 days off suboxone, and IVed 160mg of oxycontin, felt a 30 sec rush, a 20 min light buzz and that was it..
