This is a process. I know that for me to move forward at one point, I had to take a step back...just to reinforce my commitment.
I had a few drinks one night...right at about 3 months...just like you.
It wasn't fun. I didn't like it. I knew it was the wrong path.
And then it was that much easier for me to go forward with sobriety. That was about 17 months ago.
This could be a watershed moment for you too.
