There's a world of problems with your methadone analogy but I don't want to miss the real point here.
My experience is I don't drink NA beer not because of the alcohol or lack thereof but because it looked like beer, felt like a can of beer, it smelt like beer, it had that same condensation thing on the can like a beer, the same fizz and foam when you pop the can, tasted like beer (kinda)....
Then I'd wonder why I'd go out everytime and get 'real' beer.
I was still knee deep in old behaviours, and didn't even realise it.
As a former beer drinker I know it ticks all the boxes for me, and opens the door to old behaviour and old thought patterns and the desire for the buzz.
I don't recommend it.
The fact you skolled the first one would be a red light for me, and I hope at least a yellow light for you.
