Hi Raider, a lot of excellent posts here. I think the heavy introspective period you are in is typically a precursor to sustained sobriety....
Something jumped off the page to me so I did the math...197 hours sober blip and then 8 days....197 hours is 8 days.
So that is 8 days twice that you got tripped up. I know that your question was meant to address the larger issue, but I also think looking at patterns and cycles is important. Maybe it would help to be extra vigilant when you are approaching that point in the cycle, I wonder if getting over that hump would be a big breakthrough?
