Stock up on Haribo for the sugar cravings.
Get some decent quit lit - I liked This Naked Mind.
Download an app so you can count your progress. It’ll make you not want to break your streak.
Acknowledge the difficulty of what you’re doing, and treat yourself with kid gloves. It’s not nothing; you’re fighting social conditioning, peer pressure, varying degrees of psychological (and maybe even physical, but if this is the case, see your GP) dependency. So baby yourself. As many baths a day as you want. Plenty of sleep - nap when you can. Eat well, (but don’t worry about diets etc. concentrate on kicking the booze for now) drink plenty of water, mint tea, etc. You really need to up the self-care.
Meditate daily. Try the Jeff Warren 30 day ‘learn to meditate’ programme on the Calm app.
Try to take some exercise every day, even if it’s just a little walk, some gardening, etc.
When you get a craving (and you will) you just have to buckle up and ride it. Believe it will pass. It normally takes about ten minutes. You can ride it for ten minutes. Go for a walk, jog on the spot, clean the bath, punch a cushion - anything. And then in ten minutes, it’ll have passed.
Play it forward. Imagine you have that drink. But don’t imagine that first sip then stop. That first sip is what you crave. That’s it. Every other mouthful after that is chasing the relief - the dopamine release - of that first sip. But it’s gone in seconds. So you have to imagine drinking the whole glass. Then pouring another. Then another. Then trying to do the dishes or whatever while you’re a bit pissed. Then getting sugar cravings when your blood sugar crashes, so over-eating. Then going to bed and not being able to sleep. Then waking up at 3am when your liver kicks in. And the self-loathing and anxiety tomorrow morning when you realise you drank again. Imagine it all - not just the first sip.
Find a mantra. Mine is ‘No downside.’ Because their really isn’t.
Join a support group. Club Soda on Facebook is excellent.
Take a photo of yourself weekly. You won’t believe the change after three months.
I did all the above. It’s a commitment, but the best thing you’ll ever do for yourself. Good luck.
