The first thing I did when I decided enough was enough was secure funding for treatment and check in. It helped me do a number of things to point me in the right direction. For one it seperated me from the wet faces and wet places that make saying f-it so easy. Second it put 17 days sober under my belt which isn't a ton but it was way more than I had had in five years. Finially it familiarized me with meetings, the importance of a sponsor and actuilly working the steps and also having a plan to set in motion for when I got out.
Good luck
