YES!
I should go on a coffee detox again myself... I'd have a hard time giving it up completely. But I couldn't agree more, it's a very underestimated and in fact quite powerful (and very addictive) drug!
Every time I take a coffe-break (as in a break from coffee) its a tough week before my body stops showing withdrawal.
I don't know why I always come back to it though... I'm just a crackhead I guess.
Well, that was a rant. I really just wanted to say I applaud your decision and more power to you!
