Coffee or Tea (Revisited)

Not that long ago, I revealed my coffee and tea egalitarian love. I wrote that I make four cups of tea in the morning, drink one cup and put the remaining three cups into a THERMOS. I also brew three cups of coffee and scarf them down before leaving for the day.
For the past month, I have given up coffee. I still make and drink my four cups of tea, but at night time I will put up a pot of herbal (chamomile or something fruity or zesty). What has gotten into me? Well, I actually decided that I wanted to reduce my caffeine intake without going through the headache withdrawal of cold turkey.
How was it?
I've been exhausted. I mean, I will put my head down for a nap and wake up 3 hours later. I'm a heavy sleeper by nature and seem to get knocked out relatively quickly. Sometimes I'm even unaware that it's happening.
I did go to Cost+Plus and picked myself up a bag of Costa Rican coffee. I am planning on preparing one cup a day. We'll see how that plans work!
