Welcome GoodyTwoShoes. Sounds like you have a good start already - coming here and going to an evaluation tomorrow should tell you a lot. As far as suggestions go, I'd say go to the rehab with an open mind. You will most likely hear some things you do not want to hear, and you will probably be asked to do things that you do not want to to. That's going to be the case for any method you choose to get sober though..there is no "easy" solution. That's not to say that it's impossible, in fact it's very possible.
