scarlett,
I think there is a very big chance that is what they will find.
I think if your already on Sub it will block the effects of the Perc.
i think it's still going to be on same level as methadone w/d. both being long acting opiates... the w/d takes a long time. my drug case worker says he hasn't noticed much difference in w/d length or intensity between the two. i know people who switched to sub from methadone, and so far none have managed to get off that yet either.
I think when we start getting some long term statics about suboxone we will have more of an idea .One of the issues with sub is its only been available for 6 years .
Methadone is a monster that takes forever to get past....buprenorphine is more subtle, but its a toss up - its also different for everyone. You wouldnt be tossed into horrific w/d's if you took a perc - but why do you want to?
