You were satisfied with your meal last night, so you don't need to eat today?
I get that this is a metaphor for your "hunger for knowledge", but the situations are very different. You have to keep eating, every day, or you'll die. On the other hand, if you ask a question, and people answer it, it can be helpful to keep track of that information for future use.
Should you go to the hospital?
I saw that you said this to Bob but quickly deleted it, so I was surprised to see it again. Over here, we would say "take your Prozac" or something. It's considered rude.
