To be fair, we are all assuming that round of drinks was alcoholic, but he did not say so. He could have been drinking lemonade
Interestingly enough. Though th OP's story is sketchy. I'm keeping an open mind.
This is a support forum at he end of the day..
Over 30 years ago after a night out drinking soft drinks & finishing the evening with a "swift 'alf."
I found myself treating a hypo on the way back to my car parked up in a dark area.
As in sat in my seat rumaging through the glovebox & scoffing more sweets, i became awair of a police car cut into the space in front of where I was parked up.
Next thing a copper was knocking at my window. I wound it down rather gobsmacked.
Long story short they thought I was stealing my own car. But the officer had smelt my breath & decided to breathalize me..
They knew very little about Diabetes. The rules regarding hypoglycemia & driving are a lot clearer now than they were when I passed my test. All they wanted to know on the DVLA forms was are you hypo aware.
So they kept me in the back of their car making small talk for 20minutes & got me to blow in "the box."
I got a red light on the box. & was run down to the local nick, put in a room with a bigger breathalizer machine & waited two hours whilst they went looking for a mouth piece for the tube..? (The longer they wait, the higher the alcahol content metabolised in the body..)
By this time my BG was back in range. Soooo, I blew in the machine & the officer in attendance went "oh?! Barely a trace."
I mentioned that it may sound like a cliche, but I was telling the truth about the "half."
He replied, "you got to do it again. Keep blowing..."
The second reading was lower than the first & I was released without charge. With a lecture on drink driving. They even took me back to my car..
That was the first time I ever allowed alcahol past my lips holding the car keys & most certainly was the last..
We all do stupid stuff in our yoof, the trick is not doing anything that you'd regret putting lives in danger.. Including yer own.
Now I always thought the officer's handheld breathalizer device that night was calibrated lower or I had a funny metabolism with drink.?
As I mentioned, I was comming up off a low. The focus being treating & getting back in range before starting the car..
I lose confidence when I drop.
But, I found this,

Certainly I wouldn't advise drinking any alcohol if you intend to drive.
I'm going to tag in
@bulkbiker &
@Jim Lahey who know a thing or two about keto to check the link I found..
Though personally
@thatgy . You'd be best off holding your hands up based on your recollection of events.?
I got no reason to judge. You had a night out. It ended not as expected..
