Dolores, thank you for posting. It was good to see this as a reminder.
I stopped drinking for the same reason almost a week ago. Different symptoms but same story: If I keep drinking, I won't live too much longer.
Good that you are mindful of your typical cycles and habits. Look into AVRT and urge-surfing as skills to learn.
Short explanation: The part of your mind that goes "Whee!" even though the rest of yourself goes "Oh no!" is your Addictive Voice (AV). It's only a voice. Learn how to recognize it and ignore it every time. Pay no attention to the clever drunk behind the curtain.
Urges come and go. No immediate action needed. Detach and observe. They will pass. Go do something for a few minutes that needs your attention to help distract you.
I would also say that just reading SR is very helpful to me.
Best wishes for your health and recovery!
