Trees, good job on stopping when you did and getting right back to sobriety. Your situation sounds similar to what happened to me on Day 63 when I just decided to drink rather than offer up any excuses and really focus on sobriety. Like you said, I did want to drink too, especially after I got the first one in me, and then I didn't stop until I was definitely buzzed. Stop short of getting hammered though.
I'm now back on Day 43, so will be my 105th sober day in the last 106.
