Yes, I think it's possible...very possible. There are different ways to skin a cat. Some folks have sobered via this website alone...some have used addiction therapists or other recovery groups..some use AA.
I think community and support is very important in recovery...simply because it can be lonely business...and lonely is a pretty big trigger.
Although I am not a member of AA (have been before)..I am open to attending a meeting if need be...even if its just to listen for an hour...to other folks trying to stay sober.
Welcome back.
