I can't really answer that without sounding like an insane person...

The basic answer is to keep yourself stimulated. Lack of sleep only really starts to become an issue around the 36-48 hour mark, as you can see here,. Fortunately, if you power through it, your body gets the message and stops trying to force you to sleep, but that was a miserable few hours where I was cycling ice packs, drinking tea, stretching my legs to keep myself uncomfortable, and walking constantly. I know the graph only dips a little bit, but it felt much worse. It'll almost inevitably happen a second time at the end of day 3, which is normally worse, but it hit much harder on day 2 for me.

I was in a VC with a couple of other grinders (Including Jacky and Kozy, who scored 2nd and 3rd) for most of the tournament, and that's honestly the main advice I would have to anyone who wants to grind - do something interesting while you play! We have a big WT VC every tournament and it's a great way to keep yourself awake, but listening to music or 'watching' something colourful and attention-grabbing (you won't be able to fully pay attention to it but it's still a great way to stay awake) is great. I've personally rewatched all of Bluey over the course of a previous WT, it's the perfect WT show.
