Good post about coffee..but too much also not good for our health...coffee if coffee 'o' (tagline in my place) is ok ..i mean purely coffe . But if coffee (in my place if mentioned coffee ..means mixed with milk) as well as premixed coffee ..coffee already mixed with other something like herbs , creamer and etc..to enhance the taste, this kind of coffee sometime can build up some 'trapped air' in our stomach , which is believed some acidic condition happened after action by caffeine (came from premixed coffee)..I think drink coffee .. i mean pure coffee is better in terms of to enhance our freshness specially in the morning..(sure during start our job)..
