Coffee and Caffeine FAQ

Was drinking: a) 2 or 3 regular brewed at home american coff. at 7 am 2) 1 expresso with milk(cortadito in Miami) (small latte) at 9am 3) 5 same as latter between 10am and 5pm...for years (mixed in with some capuccino's/black tea/misto's etc).
Today: a) attention dissipated 2)Jitters 3)Minor headaches
no desire to go-back to coffee 4)drink green tea in the morning and water during day 5)Must eat-snack less to avoid substituting coff with snacks.
Main problem: coffee to me was a social thing, hard to substitute with water!
