A few months ago I remember reading an article that stressed the importance of taking rest periods and remaining alert on long journeys. I cannot remember if it was in one of your answers, but as it has long been my practice never to drive for more than 2 hours, I fully concurred with the article and did not keep a copy. However, the article mentioned a useful spray with a floral scent that was reputed to be a good way of refreshing oneself. It was obviously not lavender, which is used to induce sleep, but, as I am faced with making an unusually (for me) long journey in the near future, I have become interested in what that recommendation was. Can you, without going to too much trouble, indicate what that scent might have been.
