“About 15 months ago I had open heart surgery, the very first meal they brought me the morning after surgery included fully caffeinated coffee, which was surprising to me.”
I’d be far more worried about what else was on that tray.
Surviving on beef and chicken broth, Jello, OJ, and Gatorade, for 3-4 days is no fun, the last day I was in the hospital, I got a solid food breakfast, eggs, french toast, etc..
