I relapsed at 3+ years. I didn't post first, in fact I had gotten away from SR and become complacent.
Stressful events will always come. Or thoughts from the AV. So best to keep at a program of some sort.
Reading and posting helps - we feel good in helping others, and it serves as a reminder and reinforces our sobriety.
Exercise is my number 2 tool - I bike 6- 8 hours a week and it dumps all the stress.
