My friend, if you can get a hold of Iboga, or better yet Ibogaine (the chemical in Iboga) administered by a health professional, your soul-sucking addiction could receive a blow larger than you ever thought possible.
Now personally, I'm currently in the process of quitting oxycodone myself after 3 years being addicted to it; and for once, I'm doing so very successfully! At first this seemed impossible - as the withdrawals are an indescribable hell that never seem to let you rest - but I am now almost off the stuff entirely. How you ask?
1) I weened myself down. After taking 100-400mg's a day, I'm currently down to a paltry 10mg per day with 300mg tramadol (a faaaaaaaaar weaker synthetic opiate).
I found the lowest dose I could tolerate without relapsing, and started from there; not pushing it too hard, not throwing myself into excruciating pain thinking "oh yeah! I'm gonna do this!". Because after a day, you become utterly exhausted and fall right off the wagon. So don't drop too far, too fast.
My recommendation is that once you find the lowest semi-comfortable dose, drop 5mg a day, and when one of those 5 mg drops feels too harsh, stay on it for another day before dropping the next 5.
2) Don't touch methadone treatment with a 10 foot pole. The government (well, the FDA, a government organization) has a mentality of "if it gets you high, it's evil!". And so methadone, which actually blocks the euphoric effects of opiates, is the prime substitute for other opiates. But methadone has been proven again and again to only potentiate the physical addiction to such extremes that some people have suffered for up to 6 months of withdrawal before finally feeling relief. I don't know about you, but I can barely make it through 3 days within an inch of my life (in fact, the last time I did full-blown withdrawal with no weening down, by the morning of the 3rd day I was collapsed naked on the bathroom floor, all my strength gone, crying like a baby, and the paramedics took me away to the hospital).
That aside, I read a very interesting recent study that showed that heroin addicts in methadone treatment had about a 64% relapse rate, while trying a new method of gradually weening them down with diacetylmorphine (heroin) or Hydromorphone (Dilaudid) had only about a 33% relapse rate.
3) and now my chemical secrets. By doing endless hours of bio-chemical research and devising just the right chemical treatment plan, I've managed to make this withdrawal the most remarkably and surprisingly easy thing I ever could have hoped for. But, I don't know what other meds your on and therefor what contraindications may apply. For instance, if you're on any MAOI's, this treatment plan won't be for you. The MAOI's are my biggest worry really, but not too many people are on them anyway. So, here's what I did chemically to give my withdrawal a thorough butt-kicking that made it feel like it wasn't even there (while staying at extremely low doses, not being completely off).
- Lyrica (Chemical name "Pregabalin"), 75mg, 1/3 times a day. One when you wake up in the morning is most important. Then, as needed, one in the mid-late afternoon and one before bed.
- Clonazepam, 1-2mg before bed at night.
- Ativan (Chemical name "Lorazepam") 1-3x during the day. Mind you, I have a bit of a benzodiazepine tolerance, but by the looks of your post, so do you.
- And here's the big one (not that the other ones aren't important too!): Dextromethorphan drank down with a tall glass of grapefruit juice. I can't remember all the science that lead me to this conclusion initially, but here's the gist: grapefruit juice has a unique quality that inhibits your liver's production of the Cytochrome P450 liver enzyme and all it's sub-sets, including the all-important CYP2D6 enzyme that metabolizes the Dextromethorphan (in simple terms). Inhibition of the CYP450 enzyme will also inhibit metabolism of most opiates, including oxycodone, so the amount you do have in you will actually be stronger and last longer. This is actually kind of a bonus in that your before-bedtime dose won't run out before you wake up and have you waking up at 4:00am DTing.
As to the dose of Dextromethorphan? That's entirely up to you. Generally the more you ingest, the more the withdrawals go away. I personally found that after one night of being fairly high on it - but not too much - my opiate cravings and withdrawals were gone for a solid 2 days. But I wouldn't recommend actually tripping balls on it - and it's not necessary - just drink enough to keep those DT's down; you'll figure it out through trial-and-error.
All I can say is that Dextromethorphan has been an absolutely miracle, life-saving drug for me, and I don't think I could have succeeded without it. But it is ABSOLUTELY ESSENTIAL that you make sure you get a formula with ONLY DXM in it. I got Buckley's DM, personally.
Good luck to you friend. The road to recovering is a lot smoother and less scary when you know your biology, and most importantly, stay committed. I don't know if this will work for you, but personally, every time I'm about to take a big dose of oxy I say to myself "I'm going to do brain damage here. Am I really willing to sacrifice some of my mental capacity for this?"
