UN1 - I am the last guy to be a preacher here. Having said that, you are determined to get healthy, and live a long life for those around you, right? I assume this is a yes, since you have been making positive changes for the last 6 months. If you continue to feel this way, and are truly committed to a healthier (mentally AND physically) lifestyle, get yourself to an AA meeting. In fact, get to 30 of them in the next 30 days. No one there will know (or care) what your name is, and you will have a TON of experiences to learn from. I don't believe it is the only way to quit drinking and get right (mentally AND physically), but I do believe it is better than about anything else, especially if you have mental and physical issues/dependencies that are triggers.
Like I said, I'm not perfect, and I'm no preacher. It is a free, proven resource though. Take advantage if you can.
