Hi J and welcome! You and I are about the same age and share almost the same story - drinking wine alone, hiding the evidence, daily withdrawal only to cave again that night. Always making sure you had enough wine to sustain at least a couple days.
My journey started on December 31st - New Year's Eve...I tried getting into rehab but couldn't due to the holiday, so I got a mild sedative from my doctor and went to an AA meeting. I have also researched SMART, LifeRing, and other behavioral modification techniques. But I have found everyone and everything here on SR to be the most helpful.
You have an excellent outlook as far as taking what works for you with different programs. The beauty of SR is it is here 24/7 and wherever you may be.
Good luck and stay strong 💪
