So I make my own tea, I call it Faux-rizona, as I "invented" it when I was unemployed back in 05-ish, when I drank Arizona green tea by the case.
Raise water to 160-180 Fahrenheit. (I used to boil it then let it cool for a predetermined amount of time, but now you can set the temperature on your electric kettle.)
Put bag of Celestial Seasonings green tea ("authentic") in water.
Wait ... as long as you like -- I probably overdid it with 30 minutes, but that's what I did, if you want a safe starting point.
Add honey, agave nectar, whatever. Seal and cool.
When I first did this, I left the entire neck of an Arizona bottle and filled it with honey, and it was still a half as sweet as Arizona. I now barely add a lid full of agave nectar, and have just developed a taste for the much less sweet tea. I must say, I have also lost my tolerance to processed sugar, and can barely handle any sweetened drinks any more -- soda or tea or otherwise.
I now use loose leaf tea, but the Celestial Seasonings bag is an excellent starting point, and it took me forever to come up with something that even competed with the Celestial Seasonings.
You're welcome.
I tend to drink a little more than 6 bottles / day. I used to be up around a dozen. I, too, am averse to crossing completely over to water -- gotta have some taste. But like any diet, you can acquire a taste for anything, when it becomes the norm.
PS I should also say, I've recently had my blood cholesterol and pressure 6 month checkup and the doctor said, "whatever you're doing, keep doing it, you're on the right track".
