( I'm not sure it is correct to use "food" . Is it more natural to use " meals" or " dishes"?)
I don't know if your question for discussion or you're just need to help and correct. Anyway I'll answer your question because I liked it. LOL! Well, when I drink a lot of cups coffee LOL! REALLY I can't liveing without that, if I can't drink the coffee during my day for any reason that mean I'll getting a low mood. Also when I buy a new books.
