There is currently a thread in AMA that's made me post this, on the basis that this area has more traffic than AMA.
In my experience (I'm from a family of alcoholics; have been sober myself for about 15 years), many people who drink more than they should reassure themselves that, because they keep fit (often to extreme levels!), and because they drink 'only' the same amount as their friends, and because their blood tests show a normal liver function, they are 'safe'. What the AMA thread reminds us of is that it's possible to go from being apparently 100% healthy to having cirrhosis literally overnight.
Please have a genuine, serious look at how much alcohol you drink, particularly if there are people in your life who rely on you. The liver rarely gives warnings.
Thanks for reading.
