Yeah it's usually what I drink If I'm designated driver but I think most people don't realise it's 49% alcohol. But you're right if it's only a few drops hopefully it won't be picked up in a breath test. Can you imagine, "please Mr Officer I swear all I had was 12 lemon, lime and Bitters ??"
My FIL is a limo driver and had a bottle of lemon, lime and bitters that he bought from a servo which he was drinking as he drove back froma job. Got pulled over, RBT'ed and blew .06. When he said all he'd been drinking was the l,l&b, they made him wait 20 mins and blow again.. and it was down to .01. So it will leave a mouth-alcohol reading, if not a blood one.

And on the actual subject of the thread I am a bad coke addict But inly for Macca's coke (and only in a medium cup), or from a glass bottle. i have one a day, every day (but follow it up with heaps of water).
