Hey guys, I as well am fasting + studying, and I have mastered ways to make this as easy as possible on myself hahah. What i do is stay up really late, and wake up really late (only works if u don't work, and are a bum like myself) I wake up about 2-3ish and study until i get super hungry+thirsty.. about 6ish, then chill till its time to eat, then relax a bit, and study until fajr ish, then sleep all day, etc. so i basically study from 12am-4am and 2pm-5pm, give or take depending on the day. has been workin pretty well so far, give it a try. Also, gatorade for sahoor is where its at, helps replenish ur electrolytes 🙂
