I'm alergic to coffee (puts me to sleep!, if you can believe that) and can't handle the caffeine in colas or other sodas. I love tea!!
Twinings Earl Grey, and this jasmine tea that comes in a school-bus yellow square tin that I get at the Vietnamese/Chinese grocery store. After that, the Baltimore Tea Company's Chai, and also their Della Robbia. And then from the British Store I get a good brand of raspberry tea and the same brand of apricot tea.
But... I have come to the conclusion that caffeine does strange things to my body. Get too jittery on cokes, coffee makes me feel drugged, and I've come to believe that the caffeine in tea effects my blood pressure, so have had to give it up. Timely topic here, because it was just last week that I finally took all the tea out of the pantry and replaced it with herbal varieties. I was kicking and screaming, though, and couldn't bear to part with the teas yet, so I moved them down to the deep freeze in the garage. After six months there, I'll probably be ready to give them to a girlfriend.
It'll take a while to get used to the herbal teas, and I really miss the process of brewing loose teas in a pretty tea pot.
