< So, to answer your question, yes you piss out more than if you weren't
drinking alcohol.>

that doesn't mean there is a net diuretic effect.  you are still consuming,
in the case of cider or beer, 95% water.
However, there may be some adjustment of the ADH response if you drink every
day.  Someone who drinks once a week may have a strong diuretic response.
clearly our medieval friends had no such problems.

hangovers: it may be from dehydration..from hanging round in smokey
nightclubs. More likely from cogeners wreaking havoc in your brain. Or, if
you have been a good lad and drunk your copious litres of water when you get
home and whenever you get up during the night, it may be from sodium
depletion. if u keep drinking water in the belief that your pounding head is
dehydrated, the pounding will get worse until you go into a coma from
hyponatremia.
