when i read a book my eyes simply uncontrollably start closing (i can obviously no longer see) to a full halt, sleep.

i become extremely sleepy. so i lay off the laptop where im reading the pdf book and try to fall asleep so i can have some rest and then continue reading.

i was never so alive and awake while trying to fall asleep before.

this happens every time for me. when im doing anything else except reading books, im energized and cannot sleep

when i read books i get hit by a huge urge to sleep.

why is this, what do i do about it?

If you fall asleep when reading books try to drink coffee and run high bass music in low sound it will keep you awake and try to read on plain wooden chair or hard chair instead of bed or sofa

Eat a good breakfast and read in the mornings.

Typically when we’re reading, we do it in a comfortable position – sitting or lying down – in a quiet place, and often at the end of the day or after more energetic activities, all of which contributes to a state of relaxation and sleepiness.

Alternatively, if you find what you’re reading boring, the effort to keep going can be tiring, in which case you’ll likely begin to daydream, which can also bring sleep closer

First of all develop book reading habit.
