Hi JT
I have relapsed plenty of times in the past. For me its important for me to 'step up my game' when I come to anniversaries. Both important sober milestones and big relapse milestones. Don't know why, just do. I have times of year that I'm more likely to relapse as well (spring/summer for me).
Its a brain game for sure but when I make it thro tough times, my ole addicted brain learns that 'hey, I can do this sober'.
