Hey CP3, you've found yourself in here, which is huge.
Most of know when "it's time," but few of us act on that without something else acting as an influence. Often we only find the "right time" after something has gone wrong as a result of our drinking.
If you're able to find that time out of the blue, which you seem you have done, then that's a positive thing. In-other-words, you seem to know that you need to stop and you have at least taken a step in that direction. That's no small feat by any means. In many ways that's one of the hardest steps to even take.
Perhaps today, just focus on today and so on. Things WILL improve over time.
