What's the best excuse for not drinking on a night out?

[Abitlikechicken]

Really want to go out with these friends next weekend but don't want them to guess I'm pregnant!!

Can't say I'm not drinking because I don't fancy it, that won't wash...

Or drive, as the place we're meeting is just round the corner...

Any ideas??

Not making excuses works the best say you're hungover and knackered when you arrive as excuse for not accepting bought drinks. But I just bought a couple of non alcoholic lagers and asked for then to be poured into a glass, after that point everyone was too pissed to noticed tbh. Then order some/Lemo/coke/alcohol free lager. None of my mates ever noticed I was stone cold sober once they were pissed.
