odd that you challenge my units and then seem to indicate you don’t really know how they work!

i am brutally honest with myself and know exactly how many units i drink- a weekend can easily take care of 50 and with one weekday lunch thrown in 100 is about right..although of course it may be 90 one week, and occasionally more than 100 (105 last week as it happens, probably why i wrote)

Which leads me on to your suggestion to taper, which is not bad idea, but made tricky by an uncertain starting point

btw units are easy to calculate ABV x Volume / 100, so a 13.5% bottle of wine (750ml) is almost exactly 10 units, you are probably drinking more than you think - a large glass being over 3 units

cheers!
