It was consecutive but I did get up from time to time for bathroom breaks, but clearly not often enough. As for fluids I'm fairly sure I was pretty dehydrated at the time. This occurred in 2015. Since this occurred and after I learned from a nurse about the leg muscles being critical to get the blood moving out of your legs I have developed a habit of constantly moving my legs around any time they have not moved in a bit. When this episode happened I remember that I would keep my legs very still during the gaming session.
Also, 14 consecutive hours? Did you literally not get up at all in that period? Did you have enough fluids and snacks nearby that you didn't have to?
