I met a girl from my past and we got on well .she's funny welaugh all the time together. I'm a little more intellectual than her,but she loves drinking. I don't always want to be drunk when I go out with her.

You could try drinking low alcohol beer or wine while she's on the full-strength stuff

A former boyfriend of mine didn't particularly like drinking when he was out with the lads and would order shandy when they order pints

Alternatively try one to her two

Not sure what you're apparent intellectual superiority has to do with anything, but maybe just don't get drunk when you go out with her. You don't have to even if the person you're with does.

Cool Story.
