I was thinking you might have had a thundering hangover. And was unaware you ONLY drink on friday nights. For all I knew that was when you first had some, and could have drank through the weekend some. Leading at some point to a vicious hangover.
Hell, I've had a few hangovers that lasted several days and nights before. Not that many of them, but some. After the last one (caused by a bottle of absinthe, hadn't realized the alcohol content as strong stuff like the US 'everclear' is not sold here, or very seldom. And it did not burn much, its been over a decade since I'd had absinthe and hadn't realized that the reason it was not burning on the way down, at least after the first shot, was because it numbed the tongue and throat. Alcohol content, I realized, after about two days and nights of non-stop spewing every five minutes or so, and THE WORST, most vicious, horrendous, abysmal hangover imaginable, was just a tad under 75%. Took until very recently for me to be able to drink anything stronger than 15-20% liqueurs such as tia maria, schnapps and the like at all, and even then I had to fight the gag reflex.
I am now capable of drinking spirits again though but it sure took its time. And gutrot vodka still makes me gag. Suppose its as good a reason as any to spend the money on russian standard, or better.
