Liars Anonymous Community Group
A support group to provide those with a compulsive addiction to lie a place to share hope, strength and courage with others like them; solve our common problem and help others with a compulsion to lie. We aren't alone!
I find the following www site quite useful

Personally, I went on the recovery journey with a therapist who guided me through a 12 step program that was originally developed for alcoholics but works with any type of compulsive behavior. Of course their are other approaches, but guidance has been extremely important to me.
