Congrats on 6 months 2012! I thing that getting out and meeting with people, or even just going to some meetings and listening would be a good thing. Isolation is a very dangerous place to be when it comes to sobriety, being in touch with other like minded people can definitely help - whether its virually like a forum here or in person.
I think it's also very important for you to remember how things were when you were drinking - you mentioned in your earlier posts that driking caused many problems for you. Those problems will return very quickly if you were to drink again, and many times even worse than the first time around.
