I am a committed tea drinker . . . ah . . . Peet's Black Current, or, Scottish Breakfast in the morning. Black Current will make the stress leave.
But I HATE tea/coffee bagged supplies, as the best leaves are loose, like grinding the coffee beans-vs-pre ground.
I use tea sacks, and put my own tea leaf in them. This works for coffee also. Just drop the bag in your water, await 4-minutes, pull out bag.
