Stop! I need
something left to make life worth living

The carbonation is fine I hope, it is only 0.04% of the atmosphere but if it rotted things, people would have noticed. I'm not looking.
The main danger as I remember from my university days was making ultra-carbonated black Smirnoff vodka. I invented the Smirnoff alco-pop years before they came up with ICE. Just without a mixer it could knock a horse.
The CO2 has some effect where it increases the transmission of alcohol into the blood. We did it with Arberlour cask strength once (57%) and it nearly killed a guy. Great days.
