The physical withdrawal is not the biggest problem she’s facing. If done gradually enough there is no danger.
But that’s just one part of the problem. If she does not begin dealing with the reasons why she chooses substituting an altered reality for dealing with life, the gains will not be lasting.
When someone is taking 3–4 x the normal dosage there are issues beyond mere physical dependence.
Not everyone who takes opiates is an addict but for someone taking that high an amount, it’s pretty obvious.
There are people whose body is physically dependent upon these meds who are not addicts. Once the physical need is no longer there, these people can gradually decrease the amount and leave them behind for good.
But that’s the primary difference between physical dependence and addiction.
Addicts start down the road of gradually taking these meds for reasons other than solely coping with physical pain.
They begin using them for their mind altering properties as well. They do this to aid in coping with the emotional, psychological or stressful circumstances in their lives.
And that’s just escaping life rather than coping with it.
Without admitting that to themselves and beginning to deal with it, there really is no recovery. It’s possible they may wean themselves off physically (but doubtful at that huge amount) but sooner or later they will seek escape again. Usually with the preferred drug but sometimes with another substance or addictive behavior.
Without professional help OR the support of other addicts with a good track record of recovery years under their belt, they won’t have long term stability. Just a repeat bunch of hills and valleys.
This can be summed up best by the simple statement that abstinence is NOT recovery. They are distinctly difference.
It is true that abstinence is necessary in order for recovery to begin. But that is merely the first necessary step in the entire process of recovery. And the easiest one to boot.
I know that sounds a bit strange, but check in with any professional person or recovering addict and they will verify that.
Recovery requires an ongoing process of rigorous self-honesty to prevent relapse. Especially with prescription meds which are not illegal and pretty easy to obtain.
The best thing her husband could do would be to get her to agree to inpatient rehab followed by a supervised sober living program. This is where she will learn to begin facing the underlying trigger issues, get honest with herself and develop the tools she needs to STAY OFF the meds once detoxed.
They will also do a complete physical medical exam to assess her degree of pain and find alternative treatments methods apart from mind alterating substances.
Yes it is possible to do a physical detox at home with medical guidelines. And it will last however long it lasts.
But until she develops the tools to cope with the rest of her life without chemical aid it will be the same roller coaster of quit-relapse, rinse, repeat, ad infinitum.
She has essentially been escaping into a chemical fog for years and will continue to need that escape till she begins to face the underlying issues and learn to cope with life on her own.
Addiction is a complex disease, frequently subject to relapse and resistive to treatment. It’s a disease of denial.
The physical is merely the tip of the iceberg. Someone who has progressed to the huge amounts you mentioned is facing far far more than physical pain. And that’s assuming that those numbers are close to the truth. My guess would be larger than what she’s willing to admit to.
So to answer the question. Yes the conplete physical withdrawal to zero is within the realm of possibility (altho highly unlikely).
What are the dangers to look out for ? Repeated relapse into one addiction or another.
Her husband should really get himself to the nearest AA or Narc-Anon meetings on a regular basis so he begins to realize fully what he is dealing with.
