Hi Leslie and welcome to the forum.
I too had 10 years of sobriety several years ago and then really began to take it for for granted. That was a huge mistake of course. I returned to drinking and soon was drinking more than ever. That lasted for almost another ten years.
I found LifeRing and this forum nine years ago and after a couple of false starts I have just celebrated my ninth anniversary of sobriety.
I'm now thankful for every sober day and I will never take it for granted again. I know you should never say never but I'm comfortable in saying exactly that today.
Good luck. There are some great people here who helped me along the way and i still treasure their friendship and support even though we're separated by hundreds or thousands of miles.
