....There are no medications that will alleviate opiate-detox symptoms other than more opiates. Sure, benzos help the racing thoughts, and atypical anti-psychotics help you sleep long and deep, and all the other stuff for physical symptoms will ease physical discomfort....
Yes and no. Primarily as of the last few years the standard has to put someone on ORT (Opiate Replace Therapy) which does involved replacing a much more destructive opiates - di-morphine (Heroin), Morphine, Oxycodone - with an opiate with a lesser destructive drug profile. Primarily Buprenorphine (in Suboxone [the most common due to the incorporation of Nalxone to primary prevent ROA diversion > IV) or Subutex which is minus the Nalaoxone but only in special cases (pregnancy, intolerance, etc). Second to that is Methadone however this is becoming less and less prescribe (in the first case) do to it's greater abuse potential (eg, no ceiling dose).
Other than these, opiate w/d 's are usually treated symptomatically. That is, drugs to reduced hypertension, asthaesia, anxiety, depression, etc. You are right Willy in the atypical anti-psychotics are readily prescribes however don't let the fact that they're "anti-psychotics" put you off, they can be quite helpful!.
....I once decided to go through a cold-turkey detox, just to see what it was like....
Good fine (re: the paper) Willy!
I say good luck to ya mate! You're a brave man. There
can be serious side-effects from doing this essentially what's called
PAWS - Post-acute withdrawal syndrome which is basically just a fancy term for a catch all symptoms including; sweat palms, mood swings, anxiety/depression, cognitive impairment, febrile, MI's (heart attacks or angina), to death
{to name a few}. However there are way
too many variables to even begin suggesting where to begin. Hence why most people go with ORT.
I found an interesting article relevant to your question about naltrexone, or naloxone in this instance, "speeding up" or making the withdrawal process a little less shit.....
Continuous naloxone administration suppresses opiate withdrawal symptoms in human opiate addicts during detoxification treatment.....
Naltrexone has showed promised as a treatment for opiate dependance. The main issue in most studies in non-compliance.
Naltrexone has been used off-label for many things, although not many studies really have been concluded to give a definite answer in the treatment of opiate addiction unfortunately.* The main reason for Naltrexone as ORT (and in fact replace medication for many other
non-opiate based addictions) is that it's believed to play a role in the modulation of a (Nucleus acumbins > Ventral Tegmental pathway, a Mesolimbic pathway) dopaminergic pathway in the brain which amongst other roles plays a huge part in the body's own reward system. That is, you take a drug (which influences this pathway), it causes an efflux of dopamine which the boy interpreters as good/happy/love which can ultimately lead to addiction (since of course everyone wants to feel happy!
)
Just fyi; naltrexone and naloxone are
different drugs. They both are opiate (to different sub-affinities) antagonist however they do not do the same thing - don't get them mixed up!
* Word of warning, do not use naloxone to try to reverse an opiate OD. It will not work! Although working on similar receptors, they have differentiate mechanisms of actions!

I guess even for all that not all (most?) people wouldn't listen. And if the pt flat-out states they're going to continue using than.....
