Well...saying "Here goes nothing" starts you off believing it won't work. If you are serious and truly want to give sobriety a fair shot, you should seek out face-to-face support. SR is great for online support, but nothing online compares to having face-to-face support. That can be therapy, AA meeting and working the steps, using AVRT or one of the other support groups out there.
We will support you if you really want to live a sober life. Welcome to SR!
