Having the same issue right now. I tried pulling an all nighter last night but I couldn't take it anymore and woke up at 4PM. It's currently 5 in the morning where I am and I don't know what to do lol. I think I might stay up again and take a 1-2 hour nap at noon just so I don't pass out or something. It's gonna be CRAZY hard to wake up from that nap but nothing else really works for me.
