I tapered off on my coffee drinking a number of years ago. I found that if I didn't limit it to about 4 cups in the morning, I would have trouble sleeping and feel jangly.
So, I switched over to tea. The only problem was that I was using tea bags. The company I work for provides free coffee and tea, so it was a natural thing to do. But after a time I realized the tea-bag tea was staining my teeth badly, and I got tired of it. I started drinking loose-leaf tea, and I've found it a much more satisfying cup to drink. Plus the better quality tea has a lot of health benefits without the drawbacks of the tea brewed from from tea-bags. Most people don't know that most tea in the U.S. is pretty poor quality, even in the "premium" brands, and the cut-up leaves produce more tannin and bitterness than whole-leaf loose tea. I decided if I was going to drink so much tea, I might as well drink the good stuff that would be beneficial to my health.
I'm buying most of my tea these days online, mostly from a company called "Seven Cups". They have a great selection of teas of all sorts: green, black, oolongs, white, puer, flower-scented, etc. Most of their stuff is from China. One of the owners is also a certified Tea Master from China, so they really know their stuff. Their web site is real good too, with a lot of great information about tea and tea-culture. Their web-site is: http://www.sevencups.com/
I've discovered a new tea (for me at least, the tea has been around for centuries) called Puer or Puerh tea. It's named after the town that served as kind of the production and distribution center for this tea. This tea has a lot of health benefits, and has a long tradition of being favored for a number of maladies. I really like it and usually drink it in the evening. Check out the web site for more information on this tea and others.
