I've been having issues with sleep for some time now. My main issue is not being able to break the routine of bringing laptop to bed, and then proceed to do stuff on it until 3 or 4 am. Problem is that I feel pretty vividly awake during this time, in fact I like to study a lot during this period all kinds of stuff, both for work/college and personal. It feels like my brain is in its most focused state, I think because of the quietness and comfort of the night. I think it started during highschool when I'd study until late night to pass tests (it worked and I did well) and it just kinda stuck. But having shitty sleep takes a noticeable toll on me, both physically and mentally. I'd love to change but I don't know how, I've tried putting all the electronics away, which resulted in me staring at the ceiling for hours, I work out to get tired but I still can't fall asleep. I usually sleep for around 3 hours a day, and then 12 hours during weekends when I don't need to be anywhere.

If (you) have/had similar problems, what worked and what didn't? Or maybe are you fine with things the way they are?
And anyone who has experience with pills, can you share whether they worked or not?
