The only drink I can take very early in the morning is water. I might later then brew some tea or coffee but it would be a few hours after the day is dawn and I can see everywhere so clear.
But what I never forget to do to keep me focused for the day is having my quiet time in prayer with God - I don't miss that any day and that gives me a straight move into the day.
You sure have a good way to keep you relaxed and refreshed for the day. That's all that matters.
