I agree with all of the above that today is a great day one. Spend some time reading stories on here, and do a little research about different programs to help. I know AA has been a life saver for many. I like Rational Recovery, and Women for Sobriety.
I am only on day 24 and the first few days are tough. I made an appointments with my doctor and I am also seeing a counselor twice a month. You can do this.
Right now just focus on not drinking today. When that trigger hour hits find something else to do.
