I used to be teetotal and turn up my nose at people who dared to drink at danceparties.. but since dancing a lot of Salsa lately up in Auckland (which is mostly at clubs), i have found that it actually does me no harm and i have a much better night if i do have a drink to calm me down a bit before i start dancing (tend to get a little excited ha ha) ..
A good idea of how much is too much is - if you've had too much alcohol to drive, you have
DEFINITELY had too much to dance.
(and please excuse my age, NZ is an immoral country and i look a lot older than i am

)
