hello pock,
I still have not made it to a nar anon meeting! I do go to al anon meetings.
I think that they are fundamentally the same, however the difference that I have heard from people on this site is that the stories at nar anon are "darker".
I am a recovering alcoholic and have heard many many stories from alcoholics.
What I somehow understand is that though all addictions are of a similar root cause...the hole in the soul that needs mending...the manifestations of different addictions can be different.
All of this to say...go ahead and explore the al anon meetings for sure, and then fortify the experience with nar anon and SR. There is a live online video nar anon meeting on in the rooms too. I will accept the assistance of any tool to maintain my own spiritual well being. I hope you do too, because we are so worth it!! And then we get to give back too!
