I have not long returned from my regular Wednesday pub meal and drinks with friends (I think they are friends, they insult me, I insult them and we have been doing the same thing for years so I think that counts ) Last week I acquired a breathalyser, and on return from same pub I tested myself. I’m not a big drinker - 2 pints of Guinness over a couple of hours and a meal and I feel it. I tested at 0.04mg/L. The UK drink driving limit is 0.35mg/L - so I was well under the limit. Tonight I left work late and hungry so went straight to the pub early - 3 hours in the pub meant 3 pints rather than 2. On my return I again tested myself. 0.09mg/L. Based on this I believe that I could be completely shit-faced and still potentially under the drink driving limit. I know everyone is different, has different alcohol tolerance, drinking habits, etc. But I’m pretty stunned that I could in theory be in a state that I simply wouldn’t consider driving in and still be under the limit. I’m not sure of the point of this post other than to share how surprised I am at these results.
