Has anySWIY considered this therapy for addiction? It might work very well for milder opiate addiction or those who have abused opiates heavily over the years.
The theory is easily found online but I'll outline it. Low Doses of Naltrexone are administered late at night, these doses are 1/10 those used to "block" alcohol or opiate enjoyment. The naltrexone wears off in a few hours and the body responds by creating more natural endorphins than usual. This brings the bodies natural 'opiate' levels up to what a normal person experiences. This effect is similar to what happens when a bodybuilder takes ibuprofen, which suppresses natural enzymes necessary to muscle growth. The body responds by bouncing back on the enzyme level, the final result being more than usual amounts of the growth enzyme.
Also, since this therapy is being used with good success for AIDS patients and cancer patients, boosting their immune systems, those opiate addicts who get sick might be able to reduce some of the health problems.
