>>11224095How about you try it yourself instead of parroting what other people say?
Literally wake up at 2 AM tomorrw, drink a coffee but absolutely do not eat breakfast and study/work until 12 PM.
Then have a breakfast not rich in carbs other than for fruits.
Take a break of a few hours and get back to work.
But you have to push through any sluggishness.
Wakefulness can come into waves until your circadian rhythm gets used to it.
If you feel horrible, anxious and having mild disturbances in your field of vision you have to push through it.
Of course you might not be able to do it not everyone has the same conditioning and mental stamina.
