I actually thought I hated Roobios tea until I tried the Mango Chili Green Roobios tea from Republic of tea. I guess I like green roobios but not red.
I love all sorts of teas. Green tea, black tea, white tea, etc. I'm not a big fan of the fruity blends with my green/black/white teas except for a orange blossom white tea from the Republic of Tea. That is pretty good stuff.
I do like herbals though. Celestial seasonings is good for herbal teas if you haven't tried them. I don't put anything in my teas and mostly drink them cold but sometimes hot.
The only exception is I will put some unsweetened soy milk and stevia in Chai tea once in a while but I don't drink it often.
You can't out-exercise poor eating habits.
