For me self medication did not work.
I am not a person for whom moderation applies.
This got me in a lot of trouble - and was not good to my liver and other organs.
I am 63 went "over the line" at 19 and pretty much stayed there until 39
For me the twelve step programs worked ( I ignored a lot of the God stuff)
They saved my life and gave me a way to very gradually become comfortable with who I am.
Am recently self diagnosed and it explains a lot. I strongly suspect many people in the 12 rooms are AS also.
Thats my story and I am sticking to it
