Hi OP. There is a thread on here for those seeking to be alcohol free (as opposed to reducing/
moderating) - you might find that helpful? I’m sure you already know that alcohol stimulates anxiety-promoting neuro-chemicals - gaba and cortisol . So, as you suffer from anxiety, avoiding alcohol is a great step towards managing your anxiety. Taking your sertraline properly will help - and if it doesn’t, you’ll at least be able to discuss changes to your prescription knowing that you have been taking it as prescribed.
there is a massive amount of quit lit - I like podcasts as you can just stick them on when you want - out walking, doing chores, just as a background friend- and if you’re feeling wobbly, sit with one of them quietly to get through critical moments. Like the hours between 6pm and dinner(my particular trigger time) or when your partner starts drinking and you’re resisting joining in. Just go to Apple podcasts and stick ‘quit drinking alcohol’ in the search bar. loads will come up, some with episodes on alcohol-induced
Have you tried Greek yogurt/kefir for your digestive issues? Maybe stock up on some good nutrient-dense foods today so you can be taking care of yourself. How much are you spending on alcohol? Switch the expenditure to good food and /or another thing you really like to reward yourself for staying AF?
the NHS app will monitor units as well as whole free days. So helps you get into the details of what you’re drinking and when.
good luck. You are becoming addicted to an addictive substance, so don’t feel ashamed about it. You can do something about it.
