Looks like we're in the "early research is promising" stage.
Some of the concerns are kinda dumb IMO, like the claim that soldiers
should be traumatized and horrified after killing -- that a "moral lobotomy" will make them less human. That's a lovely concern, Ms. I-Don't-Have-PTSD. Makes you sound very morally elevated.
Smarter concerns are that it doesn't work perfectly (what does?), that it can do funky things to the blood pressure, that it shouldn't be used by anyone self-medicating with alcohol or other drugs (so finish your TSM cure first), and that the dosage required is rather higher than has been thoroughly tested with previous uses.
It would also be rather tricky to do as a self-cure. Normally a therapist guides you through reliving the memory while under the influence of the drug. One interesting study had people listen to a recording of themselves telling their own story . . . I might do that approach if I decide to use myself as a guinea pig.
Another issue is that it's much easier to apply to someone suffering from a single large trauma than to CPTSD from many/prolonger smaller traumas. That's the part that really worries me. Perhaps a pro is needed, to identify a few linchpins which are supporting the rest of the trauma effect. Then again, are therapists really any good at that? If they were, wouldn't we see better results from therapy? Still researching and considering.
This is potentially big. Even after we fix our addictions, many of us are still left with whatever led us to them in the first place.
If I do this, I will use the sound recording method and I'll do it when my husband is home in case I have a bad reaction to the higher dose of the drug. I have low blood pressure to begin with, and I'd just as soon not die during the experience.

[ETA: I forgot something important in this paragraph -- it sometimes causes heart attacks even in people with no prior heart disease. So, yeah, don't do this alone. This is
not naltrexone and it's
not almost totally safe.]
