My family has been affected by liver disease (successful transplant), so I have a slightly different perspective than the other posts I think.
If this thread was purely about dry January / giving up alcohol, I would just be giving encouragement. But the OP has asked about managing fears re liver damage, which is a slightly different conversation.
Firstly, remind yourself that whilst liver disease does happen, early stage disease can be completely reversed. As another poster said, I'm not saying it as a reason to keep drinking, but as a bit of an anchor when worries get the better of you.
Remember that your situation is really common . From the 90s onwards, alcohol brands deliberately targeted women of our generation. Alcopops, 90s feminism / laddette culture, linked drinking to breaking gender rules. Then when that was over we had the gin o' clock trends pushed on social media, and then lockdown when lots of people spiraled. Add into that personal and individual stresses, and it's little wonder that so many women of our generation have ended up in this position.
There are so many people in this situation. Most of them don't take the action you're taking - be proud of yourself.
I would say however, that there is a little bit of misinformation in this thread, which can prevent people from taking addition steps to turn things around / safeguard their health. There are a lot of myths around liver disease, but buying into them is not a healthy way to manage anxiety.
So.. just referring back to some of the other posts -
It doesn't take 3 bottles of wine a night for ten years to end up in trouble. Yes, it's true that the liver can regenerate itself --- but only within certain parameters. Assuming no symptoms = no problems actually stops people getting help, as there usually aren't any symptoms in early - moderate stages (and it's really important to catch it at this stage, when it can be reversed).
My best advice for managing the anxiety is to ask for a liver screen to put your mind at rest. You could try thinking of liver screening as being similar to cervical screening or mammograms. An important precaution. Unpleasant, and can be scary, but safeguards health.
Most times the screening comes back absolutely fine (as a previous poster said, they had a screen and everything was fine). Which really takes the anxiety away, and helps you focus on all the positive changes you are making
If you did decide to have a check, GP can do simple liver function blood tests. Often that's all you need to do, they'll do the tests, check everything is OK, and offer advice and encouragement. That can really allay fears
Sometimes the blood tests indicate further testing as a precaution and they refer for scans. It's actually incredibly common / thing for GPs to send people for ultrasounds to rule out problems. I do think it's a bit like cervical screening / mammograms / sexual health checks - they can give concrete reassurance to allay your anxieties and put them to bed for good - and if they throw something up, it's honestly better to have the help.
I know people are going to say we should be more focused on support and encouragement to allay fears. So I'm sorry if I've overstepped.
You are making all the right lifestyle changes, and it's not easy thing to do, so you should be really proud of yourself. Its individual choice whether to ask for screening, and many people prefer not to, and to just focus on lifestyle. Whichever way you go, you're doing the right thing in making the changes that you are.
