I got into my recovery a month after turning 55. On the 12th of this month, I have 2 years 8 months. Personally I don't believe you have to expect a relapse. My Sponsor just turned 29 years sober, she has never "gone out".
So many folks I know in double digits still are taking daily action in their recovery. Meetings, Committments, sponsee's, volunteering, working the steps with their Sponsee. Being of service to the group and individual. Basically staying connected in these ways & more....gives you a major advantage in sticking to your recovery! Be willing and open minded. And, of course, have a connection with your Higher Power!
Try staying busy and active each day of your own recovery. As the saying goes " Surround yourself with the winners"!!
You can do this!
