So does reading a book before turning the light out. Tea might help me to get to sleep, but it would get me up in a couple of hours to get rid of it. Old age is not your friend.
Sometimes what you read will keep your mind focusing on what you’ve just read. You should be thankful then that tea gets you up during the night. One old guy was asked how he managed to live so long and he said it was tea getting him up several times a night. :)
