3/4 bottle wine a night.....

[frostyfingers]

My DH drinks about this much every night. It has no effect on his behaviour, but I'm worried that it is too much to be good for him, and that the amount will gradually creep upwards.

He has always enjoyed a glass or two (I'm not a drinker), but over the last year or so since he joined a wine club the amount has increased.

Am I fussing too much, or should I say something?

I'd say it's up to him really. If it does creep up and become a problem, that is the time to tackle it. I can understand your concern being a non-drinker but if that's his release in the evening there are far worse vices he could be resorting too .
