We have our medicals next week and DH was looking and saw that they check urine for kidney function (AKA alcohol consumption) He usually has about 2 bottles of ale a night (2.5 units each) 5 nights a week. He is at the upper end of the recommended limit for a man and once every 4-6 weeks goes out and has a "binge". Should we be worried? His mum keeps telling him he is an alcoholic but he just likes a drink. It is really rare that he goes out and gets drunk even though his mates are young free and single and can and do drink to get drunk regularly.
