You need serious exercise, you will then be exhausted and sleep easily.
In modern life people do not do enough exercise.
I go to sleep around 11:00, and wake up at 18:00. i start work @22:00
I finish work @ 08:00,, so its roughly equal times i am awake before and after work.
I mean, I was training more than most and had enough issues I had to be prescribed pills - so 'exercise' isn't always the answer. Also when your running on 2 hours sleep over 3-4 days - it's almost impossible. I assume you've had some insomnia?
Things I done to resolve;
I already exercised heavily, like an hour a day would be a short day and when enough sleep most days off would be 2-5 hours of cycling. But during the whole sleep issues I had, I barely exercised at all due, I could barely function most days - I also already eat healthy (as in I cook fresh for nearly every meal) I changed all my sheets, quilt, pillows to some good quality stuff (not sure if this was placebo, but even now I still keep it to a high quality), I stopped TV/Gaming (before bed) and tried to read as much as I could before bed, replaced my phone with an alarm clock. It went away eventually, but it was probably because I changed from working days/nights to just days.
I also used some mediation app - Calm. It actually did help a lot, sometimes. Try everything though, but stick with it - some yoga an hour or so before bed. Waking up on the weekends at the same time as weekday is important for me too. For me it was routine that finally fixed my issues, or at least I think it was.
Those sleeping pills could get easily addictive if you let them, so good luck.
