Coffee keeps some people awake. It doesn’t bother me but one year in the bungallow colony, my friend came to my porch as I was sitting enjoying cup #…I don’t even remember. I invited her to join me which she did. The next morning she came over to me looking very red eyed. She said “That WASN’T decaf, was it?” 🙂 I had no probs sleeping, but she was up half the night.
Coffee does have some good side affects according to some people.
