Why so early? Well, I had my health assessment at work today and to lower my blood pressure I decided to lose some water weight and go in dehydrated. It worked well enough as my blood pressure came in at 120/84. A lot better than when I donated blood and it was 150/95.
About being dark out... It is easy for use to come up with excuses not to exercise or for a reason to eat something sweet. The main thing is self control and to have all things in moderation.
