My error. I did 3-4x in the 50s, then quit. (I was a milk drinker) Read the part of my post about (fizzy) cream soda.
In Scout summer camp (late-50s), we tried using Coke to “tenderize” some meat. It burned the meat up, shrunk it and turned it brown; like shot leather. None of us touched that cola stuff after that.
