For me the problem is what happens when I do decide to drink. I can go long periods without drinking as well but when I do drink I can't stop at just one. I drink until I blackout. For this I know I have a problem. I am not a regular person when it comes to alcohol. Don't feel like a fraud at AA. if you want to go then go....there is no prerequiste. If just sitting there listening to other people helps you then it is worth it. You listed some things above that somewhat indicate you do have a problem with alcohol. You may not be a full-blown alcoholic but when you drink bad things happen.
