y'all i've been studying for like the past 7 hours from 9 am but I'm starting to get shaky vissions and sudden cold, also my hands are sometimes shaking too. I am so tired like I am TIRED, but tmr is final exam for semester 1 and since I prolly has adhd so I literally skip the past 3 days to do my other delayed assignments not focusing about this, wharra do now
get some rest and eat properly. Studying without rest is counterproductive (your brain doesn't process information to keep in memory until you fall asleep)
Not to mention your brain uses the most energy of your whole body (~25% of all consumed calories)
