I have the same thing. For example, if time permits, I begin to read immediately after breakfast, that is, in the morning, when I get enough sleep. Or drinking a mug of coffee. I agree with "small portions". Divide the number of pages planned for the day into 3-4 parts and devote at least half an hour per sitting. Long reading for 2 hours at a time is really very tiring and it is logical that you start to fall asleep. Before going to bed, I would not advise reading, the more difficult literature for the brain. I can't even hold out for 15 minutes with a book in my hands, especially after a hard day at work. The brain does not perceive the text in any way, it is necessary to re-read the paragraph, etc. As for the films, the same is true. Start watching at least 7-8 pm so that by 9-10 you will be in bed.
I suffer from the same problem. My advice to you is, do not read lying down, or leaning back in a soft chair. It is best to do this in a position that does not lull you, and healthy sleep is very important here. Failure to comply with the work and rest regimen often forces us to be overwhelmed in the evening, and then any information is difficult to assimilate (if, for example, did not sleep last night). Think back to your school / college years (if any) and how you did your homework. Personally, I have always done something like this while sitting at the table, but I don’t know about the others.
Or, alternatively, do not read later than an hour or two before bed. Doesn't help - write, we'll think about it.
Maybe you should read "in small portions"?) If I read for more than one hour, then I also start falling asleep, this is natural. It was also exhausting for me to watch films, I paused 100 times, came back, but this is most likely from restlessness. Perhaps you have problems concentrating (I don't know how to treat this, I just drank glycine and tried to pull myself together)
This happens due to the fact that the brain is greatly "overloaded" from the excess of new information. This cannot be overcome right away, just read what you need every day, over time the brain will get used to receiving the load. You can try changing your daily routine. If you fall asleep, then the body needs it. A lot of energy is spent on the work of the brain, this is justified. Rest more, eat more, concentration worsens due to I LIE UP AT THREE NIGHTS WAKE UP AT SIX IN THE EVENING I AM LAZY TO COOK BY SING BICHPAK I INTERESTING WHY I DON'T IMAGINE ANYTHING COFFEE SHOULD BE DRINKING BETTER ENERGY. In general, the brain requires rest, which means it doesn't get enough of it, it seems to me so.
