I know a lot of people who knock the booze on the head during this month to allow their bodies to recover from the festive, if not longer, pasting they have endured. I wish them luck and hope they can achieve their aim.
I have also glimpsed through a lot of headlines where "experts" have advised against this practise going further and suggesting it may even be dangerous. I don't bother reading the rest of the article as they rarely are experts and within six months they will be contradicting their own advice.
Me? I keep on doing what I always do and that is have a load of beers when I go out as usual. I now try and restrict myself to doing this only twice a week and feel much happier in doing so.
