I've never tried myself, though in the past I followed with interest the papers from Crain & Shen concerning the role of ultra low dose naltrexone in inhibiting hyperalgesia-inducing excitatory opioid receptors. These papers might be worth reading before you eventually try.

Thank you. I will look them up.

We used Naltrexon with success but it was not used in conjunction with the taper off period. Rather, it was used in a relapse prevention strategy after detox or other controlled environment initiatives
