I am on day 17 of coffee-free life. I mean, not caeffine-free, but coffee-free. So yea, I have started drinking green tea and black tea, but I have completed switched off coffee.
Feels a little worse than my ice cream-free life (4+ years now!) mainly because at work, going for coffee is actually partly a social thing and partly just an excuse to take a break. And that smell. Oh my gosh. It has been difficult to stay away.
Of course, I have also started consuming the Starbucks Chai Tea Latte with Soy and whipped cream. Lovely! The more I drink it, the better it tastes.
Maybe it is a good thing that I gave up coffee. I would have never formed a liking for Chai Tea Latte 🙂

Good you differentiated coffee-free vs. caffeine-free. Chai-tea latte contains 50mg of caffeine as compared to 65 in cappuccino. So not as much difference. Found this off the web:http://www.cspinet.org/nah/09_06/latteland.pdfcheckout page 3.
@samir: lol, yes, I know the difference between coffee-free and caffeine-free. In fact, I love coffee more for the taste and less for the ‘boost’ that caffeine gives. 🙂
