1stepup, I would get a temporary sponsor for AA, one for NA, and one for CDA (I happen to like their meetings best). It takes a while to find a sponsor "for good" and temporary gives you a chance to work with different people. Listen to each, and don't fall into the dead trap of saying: "But my other sponsor said...".
We are all only people and there are many ways of sponsorship. Also, when you go to a meeting raise your hand and ask if anyone is going to coffee etc. and join them. These groups are never "closed" so jump right in!
