For those who - like me - are forbidden caffeine:
I recommend Twinings English Breakfast Tea, decaffeinated.
When M.D. told me "No caffeine." I tried many many brands in search of a good cuppa and the Twinings is the only one that is the same taste as "real" tea. Black tea. With skim milk and Splenda in place of sugar, please. Thank you.
As for tisanes I like Blackberry tea and Orange Spice.
Have never been a fan of Earl Grey - it's the bergamot I don't fancy. And contrary to some opinions I am* a civilised person
