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).
I agree with AnagrammadiCodeina that postponing sleep is not advisable. It causes more problems in the long run than it is worth. However if you insist that it is needed to reach deadlines, things that keep you awake are caffeinated foods and beverages like coffee, green/black tea, and energy drinks. Or foods high in sugar, like candy and chocolate.
