This my friend is called delayed procrastination

You subconsciously try to have a late night knowing that u have to work tomorow and try to let’s say try to have more time for your self that it affects your sleep

Here is a trick, u need to train your body to sleep early. I used to go to bed at 2 am and wake up at 6am and feel tired and think I should sleep in more but this is not the case. You end up tiring yourself out

Our body has a sleep cycle, light sleep, deep sleep and wake up, if h wake up, do not try to sleep in again. I repeat do not!

This is because the body will go back into this cycle and u wake up feeling even more tired because the cycle isn’t complete and u wake up abruptly due to alarm

This is what my shrink shared, in the end, I train my body to sleep by 11 and auto wake up by 5.30 or sometime earlier so I can work out. I still don’t get 7 hours sleep so I need to refine this further by trying to sleep earlier

You can get a way with lack of sleep when you are young but once hit 40, it will come crashing down on you
