re: Ovaltine.
LOL, that’s also my story with the same nasty results.
There are few experiences of that time in my life that are available to me now days, but that one is still vivid. It will probably be the last one to go. I can still see that glass of milk sitting there, with globs of black stuff swirling around in it, and me taking that first big, greatly anticipated gulp, expecting a taste not unlike that of Nestles or Hershey. My first big gulp of iced coffee, thinking it was iced tea, is right behind it in bad memories of my youth.
