How do you sceduled your day? Were you going all in and did nothing except working on your game?
I for my part went all in and pushed through the first like 40 hours until I was so tired that I've spept for around 13 hours. Which was kind of an obvious outcome. I think next time I try to stay somewhat on my normal sleeping schedule because thinking gets kinda hard after being awake for more than 24 hours. But except of eating I really did nothing else the whole weekend.
