Hi Imran_15, sorry no one responded to your thread straight away, we are very busy.. but please don't bump it, we'll get there eventually!
I'd say minimum 24 hours, probably more like 48 or even 72 but I don't know for sure and it will vary depending on dose and personal metabolism.. basically, you'll need to be withdrawing from the bupe.
If the bupe is entirely out of your system (and you are in WDs) you should get the full effects, but otherwise you will get some dulling of the high.. I don't know what oxycodone dose is equal to 8mg buprenorphine I am afraid and I don't think you should go by that conversion anyway, so I don't really know what dose you should take. Your tolerance will not be back to 0 but it is complicated by buprenorphine only being a partial agonist, which is why conversions don't really work.. as always, if in doubt, start low and work up.
The nod thing is related to the previous questions, really. If the bupe is out of your system and you get your dose right, then yes. You could also OD and die. Go steady..
Also have a think about whether you will be satisfied with just one weekend on oxy and what this might do to your maintenance.. not preaching, just feel compelled to mention that
