It's very courageous of you to look at yourself and your behavior and take the first steps in recognizing that you need to make some drastic changes in your life.
I remember not-so-fondly those days of the silly alcohol rules I made (then later broke) to convince myself I didn't have a drinking problem, including the "don't drink until after 5 o'clock. Admitting that my drinking was causing me problems and that it was controlling me and not the other way around was an enormous leap for me. I hope it can be for you also. That you came here and admitted you have a problem and solicited support seems to me that you are on the right path.
Good for you and I hope you keep coming here and look into other real life support, like AA or whatever suits you best. You don't have to do this alone.
