Just wondering if any has any tips and tricks for beating my arch enemy, the breathalyser.

I HATE THAT C^&T

i once thought i was busted for shure, just left some pub with me mates. Got pulled up, a mate had some maccas chips, i stuffed a whole large chips into my mouth, cops had to wait for me to finish. After my mouth was so dry, i took the breatho and got a 0 reading....fucks me but i felt smashed, bit like i do right now.
