sillylittlemargaret welcome back. It's hard to make that change of thought process. It doesn't always happen at the first hurdle. It takes time to embed in. Just keep going. It will click at some point. It took me a long time.
You say "can't drink". The rebel in me would rise up at that and say "yes! I bloody well can! Don't tell me what I can and can't do!". If you change your thought process to "I can drink but I choose not to" that may help. It did me.
When forever seemed too scary, or a year or even a week I used to say to myself that I can drink whatever I like tomorrow. Just not today. And tomorrow I would say the same. Then it becomes habit not to drink and that makes it all a bit easier.
And these days that were especially hard (Friday nights for me) I would say "I can drink whatever I like later on. But not right now". Hour by hour some times in those early days.
Sometimes it would piss me off and I would be grumpy, sometimes I could laugh at myself and go off and do something else and the urge would pass. Other times I would go to bed just to get the evening over and done with. And start anew the next day (without a hangover I hasten to add which made starting that day anew so much easier).
The more times you get through your particular witching hour the more you start to believe you can do this. And you can. Wendy is right. There's no magic wand that anyone has, it's just about making a choice in each and every moment. Sometimes that choice is easy, sometimes it is so god awful hard it hurts but then the easier times get more until you find yourself not even having thought of it for some time.
It might be helpful to unpick your times that you have had a drink, either on here or journalling or talking to someone in real life. What was the trigger? Is it the same time of day, or day of week? Were you tired? Bored? Annoyed?Hungry? Sad? Lonely? Was it a habit?
And, for me the biggest thing was always my toolbox. What tool was needed that would answer that particular need? A rest? A bath? An AF drink in a nice glass? A walk? A change of scenery? Bed? A cuddle? Sex! A chat with a loved one or friend? Swim. Book. Food. Sweet treats (which I needed a lot of at the beginning). Cinema. Yoga. Exercise. Shopping for something nice. That amount you would spend on booze there and then? Go buy something to wear, or for the house, or treat yourself to coffee and cake at a cafe.
It's not just about stopping something and feeling there's a void. It's about filling your boots with much more nourishing, nurturing practices that will scratch that itch, that will answer that need you have without resorting to your usual answer of alcohol. There are so many more ways to fulfill that need, it's just about finding them and trusting them.
