Have I tried Regen ZP you mean? Yes, for two weeks on the recommendation listening schedule, even two loops as a possible “hard gainer”
If you meant other methods, I won’t mention them by name but various styles including counselling, energy work, inner child meditations, Reiki etc.
This has been so far 20 years of self help starting with OG subliminal tapes, hypnosis and therapy. Only Dragon Reborn is the only sub to hav made enough of a difference to the level of trauma.
I know subs aren’t supposed to do all the work, however ZP, if its going to work for me will either need Elixir ZP (as you’ve said it tunnels backwards into childhood) or maybe Dragon Reborn ZP.
Summary
Subs aren’t supposed to do all of the work of course and medical advice disclaimers still apply. I’ll give Regen ZP the recommended month and see if the healing will sneak up on me.
