hey rustic
its a tough call...if I had the legit problems you do I doubt I would even have the desire to stop the oxy(I was taking the same amt. before switching to heroin)...you are a stronger person than me.
as far as the meth/sub...you really need to wait until you are in full w/ds, i.e. you feel like you are dying, before you take it(sublingually as dave said, and keep it under your tongue as long as possible) I would start aout with 4mg and wait about an hour. If you still feel sick after 1 hour take another 4mg. This is plenty,
suboxone is often overprescribed. If that anount does not cure the w/ds then you probably didnt wait long enough after the last
methadone.
Like i said I was taking about the same amt of oxy as you (dave- 400 mg is not a huge amount?!?!) and have been on sub for 6 mos. started out at 8mg a day, now down to 1mg/day. Sub doesnt do much for pain, but I have lees pain now than I ever did while taking oxy. When you are on narcotics for so long, I believe your body becomes hypersensitive to pain, maybe even manufacturing it, in an effort to ensure the supply of dope. Many addicts in recovery can attest to the reduced amt. of pain since stopping
good luck, whatever you choose to do.
