I have only been sober for around 90 days and I only use my daily visits to SR for support.
There is enough support here for me to have not had the urge to drink.
I use the class support thread here as my main inspiration and sounding board.
Some of us have slipped but most everyone has come back after a relapse and got back on the wagon.
I think anyone can do it with just SR if they really put the effort into it.
