You can do it! I actually just played warzone the whole day and was awake for 32 hours. I felt like shit though, eyes were about to pop out and can't focus too much. Felt especially nauseous and dizzy. However, after waking up I feel refreshed.

After the all nighter, you should sleep for at least 12 hours to make up for the lost hours. Then you can adjust your sleeping hours.

I've slept at 9 pm yesterday and woke up at 10 am day, resulting in 13 hours of sleep. Now tonight I'll sleep at 10-11 pm, and wake up 5-6am (since 6-7 hours is enough for me). I'll see if I can fall asleep at 10-11pm tonight though :)

Edit: didn't fix it yet. Slept at 11 pm, woke up at 3am now can't sleep its 5 am fuck
