Why not try AA? It has worked for a whole lot of people, myself included. I went kicking and screaming to say the least, and it's the best decision I ever made (after I quit drinking).
Your multiple questions about wondering if you can just keep going on your own....most of us who have stayed sober for any amount of time (I just passed 10 mo) have used a solid plan of action, not just wanting to be sober. That last part may not always be the case; the former is your constant.
Keep sober today- good luck.
