I dug out a couple of cases of soda sitting in my cellar...
I had one can and it tasted like it was too salty. So, I threw it away after I didn't finish it. (I attributed the bad taste to a regularly occurring reaction I have to various medications.) A couple of days later, and another can and it tasted like crap too. So I open the other case, different brand and flavor... It tasted like crap as well!
I finally figured out that I should probably look at the cases. Both of them expired in 2016!
Aww fuck! I so wanted to sugar-up today
