IMO, each relapse is harder. At least it has been for me. I'm on Day 16 of my 2nd relapse. I was originally sober for 14 months. Stupidly thought I could just have a few drinks. That relapse lasted 2 months. Went back on the wagon for 3 days and started drinking again. This relapse lasted 6 months and cost me almost everything, including my health. For me, I have finally realized that alcohol will kick my ass every single time.
I think what works is finding a program that works for you and stick with it. Do not let up. It's when I let up that I thought I could handle it. And I couldn't. And I never will be able to handle it. A sober life is so much better than any drink could do for me.
Bottom line is that our addiction wants us dead. Period.
So, I don't recommend even dangling your toe in that toxic water. Keep staying the course & learn from me and others who have faltered, stumbled and clawed our way back to a sober and more rewarding life.
