Gary - I'd agree that a bottle a night is too much - I do 1/2 bottle as P has the other 1/2! but that would also be on the back of a can or 2 of Stella for me. that's been my regime for some time BUT we have made a sea change this year and cut out either the Stella or the wine - usually the wine, and just stuck with a can of Stella. which is more calorific - beer or wine - I'm not sure.....
we have also given ourselves the added incentive of every bottle of wine we don't drink, a fiver goes into a buffalo clip - we're onto a bigger buffalo clip now and there's over a few hundred quid there for some indeterminate purpose sometime
it's a start as both of us realised we were drinking a little too much anyway on a regular basis (moderation has different meanings I guess!!) and as I am not exercising so much (due to injury) to burn it off, then I am seeing the knock on effects on my already ample waistline. something needed to be done.
but I guess the good point is that we can recognise these issues and do something proactive about it when it needs to be done - the problem for many is that they can't/won't do anything about it and matters get worse or they don't see improvements in performance
