I was about 3 months sober before I went to AA. It came down to me thinking, ok I feel great, I'm not drinking, but is this all there is? Just not drinking? I started wondering why I drank, what I was doing by drinking and did I still want to behave that way?
I agree with Rob. Read the Big Book. Find out if it's about you. If it is, then get a sponsor and work the Steps.
