last 2 months been up and down taking oxy everyday. doses at a minimum around 20mg upto 120mg, whatever i could mathematically decide was ok until i could get more. I managed to get myself down to 20mg a day then picked up another couple of boxes of 20mg oxynorm and it all began again. next thing i know im at my doctors office begging him for more. here i am.

i took a week off work to give myself time to kick it. since tapering wasnt working... its been about 3 days now since ive had any and im feeling alright. im fucking fiending and fighting a battle to not get some. i have a 20mcg/hr norspan... i want to know given my low tolerance (i feel happy off 20mg, but 60-80 will get me a good nod) if this will fucking drop me or if i will be ok. doing the math its only 0.5mg/day which i know i could tolerate, but something is telling me there might be some other math im missing or some shit.

your help is very much appreciated!
 
Some of the parts of the math that you're missing (at least from what's above; you probably know most of this already) are:

- Relative strength of the two opioids (bupe is at least 20x stronger than oxy)
- Relative bioavailability of the two opioids via those delivery methods (oxy oral: ~90%; bupe transdermal: ~50%)
- Half-life of each (oxy: 3-4.5 hrs; bupe 20-70 hrs, so doses 'overlap', meaning more in bloodstream)
- Oxy is full-agonist; bupe is partial agonist-partial antagonist (so can partly cancel out effects of other opioids like oxy)

All that said, dosage conversions don't seem to be an exact science, since people's individual metabolisms react differently to different drugs.

I've made a sudden switch from oxy tablets to bupe patches myself once, and it was really rough; only worth it since I was on the patches for a long time (for chronic pain), so the few weeks it took my body to fully adjust were nothing in the big picture. So if you do it, don't expect to feel great right away.

If you were to use it, given your present low tolerance and that you're trying to wean yourself off opiates, you could try cutting the patch in half (for 10mcg/hr dose) or even quarters (for 5 mcg/hr). You just need to find something to stick the cut edges down with; ideally tape but in a pinch a couple of bandaids should hold it down reasonably well.
 
The math i was going from was 20mcg/hr (0.02/hr) x 24 hours in a day to give me 0.48mg/day. Is this wrong?

I had considered cutting the patch in half but heard it can leech extra from the cut.

I had overlooked that by the second day the dose would start to overlap due to the long half life so thanks for pointing that out!

I'm already essentially out of any withdrawal i just want something in me to stop me wanting to go out and score...

Thanks for your help :)
 
just wrapping this up.. i've had the patch on for over 72 hours and it has completely taken care of the cravings i had to go out and score and it has done nothing more than make me feel great. i essentially just feel normal, but with a bit more happy thrown in. the patch strength was not an issue even with a low tolerance to opioids. if anyone else is ever curious if the dose will be too high, here may lie some answer. peace.
