So I went to the doctors , well nurse to be exact for my 40+ MOT and she said do you smoke? I said no . She said do you Drink? I said a little . She said how many units a week do you drink ? Well here's the problem, how do you keep count ? like a little notepad or something . Casual drinking at home doesn't count in my drinking maths abacus . She said give me a guestimate so I said 40 units a week , aghast she said you need to half that....i said , I just did . Your units please bbs's .
