You guys seriously need to try to get memantine scripted, alternatively one of the long-acting dissociative RCs or give DXM a try if you're not scared of robotripping. With deschloroketamine the withdrawal from bupe was flaw- and painless, as well as with memantine from morphine, it was almost too easy, I just was anxious of what might come, but nothing did really. It requires some serious dosages but is very effective. The interaction of NMDA with mu opioid receptors is well documented and somewhat studied in PubMed papers, just nobody uses it clinically and I really wonder why, I guess they just don't care because 'it's just junkie folks'.
