This might sound heretical to most, (it did to me until I tied it,) but have you ever tried drinking a cup of plain hot water, boiled for tea but without the tea? I know... it sounds pretty weird. I had a colleague who used to drink this with her meals and I used to laugh at her all the time. All she would say is "try it yourself."
She never argued. She never defended. She'd just say "try it yourself." After about 6 months of watching her and laughing, I finally tried it myself... These days I drink it often. Not as often as tea, but I do drink several cups per week. Try it yourself...
