My first drink of the day has to be Tea, I then feel the day has begun, if I am on a work day my next drink has to be a cup of coffee, if it is a day off I can have another cup of tea but then move on to coffee.
I always drink black coffee at work mainly because I was too lazy to keep taking milk into work but I do prefer it that way. I have stopped drinking latte's as I find them too milky now.
In summer I do throw in some fruit teas at work as they are quite refreshing.
