@mynameistillian This is a difficult one. If it were me, I would pick 'go rest', because I find that if I rest in the middle of enthusiasm, it's relatively easy to pick up the flow the next day, but with a fresh mind - and that means I will get way more done anyway, because sleep deprivation is bad for productivity (but it's hard to notice it).
But I don't know if it works the same for you.
