Responsible drinkers don't exceed

According to the side of my Kronenbourg Blanc white beer, I've had less than 1.5 UK alcohol units (one bottle). Responsible drinkers don't exceed 4 daily units (men). I was away eating the first decent meal I've had for nearly 24 hours, so I'm already past tipsy and up to drunk. Thanks to my body's love of sobriety, however, the time it has taken me to come upstairs and write this has seen my intoxication level fall back down to tipsy again, on my way to sober.

I had best get going to that housewarming!
