naomi - // You suggest wrong. A hangover is rather more than that. //
I do know that - but obviously, hangovers vary for numerous reasons - the amount imbibed, and the experience and constitution of the imbiber being just two of them.
We can't really offer hard and fast examples to debunk a cliched joke from an unpleasant deceased 'comedian'.
I have had two hangovers in my life, the last one was well over forty years ago, but the experiences are vividly imprinted on my brain, and I do believe that even if i had drunk that amount of alcohol because i enjoyed it, rather than, as I did, drunk it to see what being drunk was actually like, I still would have sworn of alcohol the day after, and stuck to it!
My experience was the same as being sea-sick, for a couple of hours, you are afraid you are going to die, and then for the next couple, you are afraid you are not going to die!!!
