>>11092286Since nobody seems to be giving detailed advice here are a couple. I've done all of these to varying success, experiment at your own risk.
Eat less, this kept me more alert. Week of finals I always ate a lot early in the day and quit around 11-12, then studied until 12am-1am without getting tired. This was usually coupled with alternating coffee and tea (energy drinks early, then alternate espresso, tea, coffee, tea, coffee).
Alternatively, try a hard reset day, it will be worth the lost study hours. Near the end of my college career I gave up on the not sleeping thing, confidence and alertness are king. to reset wake up around 5am, go until 9 or 10, go to sleep. repeat. you'll do better trust me. If you dont have the time to reset your sleep schedule stick to the alternating caffeine but be careful and always count your total mg. never drink more than one energy drink a day.
