The last time I was hospitalized, I went into ER at 11am and wasn’t admitted until 10pm - they didn’t feed me while I was in the ER, and food service was over by the time I was admitted. I begged a nurse for some food and was given a tiny microwaved dinner that was so bland I had to force myself to eat all of it, knowing my hideous migraine wouldn’t get any better by starvation.
In other words, the food was terrible and there wasn’t enough of it.
