Probably placebo: i felt like my head was in the same place but my body was upside down.
This went on for less than a half hour. After initially noticing this felt completely normal. Never brought this up online but never met anyone irl who experienced this from normal boozing.
Sometimes we still get it and i drink it watered down bc its just so dang tasty.
For me that's the actual danger of absinthe. It is indeed ridiculously easy to drink and does not impart any of the 'fire' typically associated with spirits. And I also got the same sensation of 'body upside down'. I relate it to just how quickly my blood alcohol shot up.
Because it was "the room was spinning" and that is a common symptom of alcohol, I also can't claim that it wasn't a placebo effect or just alcohol sloshed memory, and most people won't believe me in casual conversation, but anecdotally it felt so weirdly different than normal alcohol "the room was spinning".
All I can do is confirm that Absinthe drunk is different from most other typical alcohols kind of drunk. That said rum drunkeness made more beligerent drunk than normal drunk.
Its possibly due to trace amounts of Thujone [1], which strangely wasn't referenced in the article.
While ranked lower amongst enthusiasts, I’m partial to Kübler Abinsthe. It’s always a great euphoric drunk and without the head heaviness of many alcohols once you get to a certain level of inebriation.
