Disclamer: I haven't slept in over a day and idk if what I write makes any sense, I will adjust it after I wake up. Sometimes I do dumb stuff and end up not sleeping, other times there simply isn't time to sleep/rest as needed(assignments and lack of planning ahead). Any advice on how to stay awake for longer periods of time(preferably functional/not in a zombie state, I'm looking for 1 and half day of not sleeping max) and your favourite way of recovering from these sleepless stretches of time(other than sleeping of course).

Edit: thank you for your replies, I woke up a few hours ago feeling better. I am going to try to properly recover today. If you have any sleep deprivation recovery tips, please let me know and remember to hydrate.
