I've just reached 90 days for the second time, only the last time I acted out on day 91!
There is a great difference between now and then, as then I was--as they call it-- a "dry drunk," without doing much to stay clean. But this time it's with 3 times per week live meetings, plus another phone meeting, having a sponsor, doing steps 1 through 7, sharing with friends, and a lot of surrender and prayer. That's how I got here.
I always say in the meetings, I haven't done anything to keep me sober, I am just working the program and Hashem has kept me sober.
