Recently I have been quite heavily drinking beer, and noticed a strange effect: apparently an addiction developed but not to alcohol but to CO2.

Basically, now I cannot satisfy my thristyness with non-carbonated drinks, such as tap water, tea and milk.

Today I felt thristyness all the day despite drinking a lot of milk products and tap water. All the day I was drinking and pissing, but still was thristy. Finally, after 4th glass of tap water in a row, without any hope to combat my thristyness I went to a store and took a bottle of carbonated mineral water.

Instantly when I started drinking it my eyes filled with tears of satisfaction and the thristyness went away.

So, I suspect I developed some kind of dependence on CO2 dissolved in water.

  • Most carbonated mineral water is a little salty. It's possible you were low on electrolytes. This has nothing to do with being addicted, but just that you needed something, Next time you feel that way try eating a salty snack and see if you experience the same relief. – Kate Gregory Jun 23 '17 at 0:48
  • @Kate Gregory no, salty food (such as fish) does not help. Also, there is salty milk product "Tan" which has carbonated and non-carbonated versions, and only carbonated one reduces thristyness. I suspect, this is because CO2 affects drink receptors stronger, so that normal drink no longer felt by those receptors. – Anixx Jun 23 '17 at 2:12

    there is no such thing as "drink receptors" though – Kate Gregory Jun 23 '17 at 11:06

Humans get addicted to alcohol, caffeine or sugar in these drinks. Not CO2! That's just not possible. CO2 it's just very hazardous in high concentrations (see health effects of CO2). In carbonated drinks the concentration is low though.

What is the carbon dioxide content of a soda can or bottle?

Carbonated water itself might not be addictive, but if you feel something is wrong with your health please see a doctor.

Health effects of CO2:

headaches, dizziness, restlessness, a tingling or pins or needles feeling, difficulty breathing, sweating, tiredness, increased heart rate, elevated blood pressure, coma, asphyxia, and convulsions.

    While I agree with the gist of your answer, your references to CO2's dangers are very misleading and totally irrelevant to the question. The dangers of CO2 are from breathing it, not drinking it. The worst effect that drinking CO2-infused beverages will create is belching. -1 for that. Remove the toxicity references and I'll remove my downvote. – Carey Gregory Oct 17 '17 at 1:43
