Heres a wierd thing that always happens to me.
On school days I have to be awake by 6:00 and I always feel very groggy and unable to get out of bed.
On weekends when there is no school I’ll wake up around 5:30 and feel wide awake.
Anyone else have experiences like this? Anyone have any ideas about why this is? 
Assuming that you go to bed at about the same time, there are three possibilities:
1: It’s purely psychosomatic merely based on your attitude.
2: It’s party psychosomatic mostly based on psychic stress and/or brain overflow.
3 a) (depending on what you do weekdays/weekends): On weekdays your body needs more sleep. (Do you do sports only weekdays, especially endurance-training or strength/muscle-training?)
b) Your mind needs more sleep because you learn so much or do not get enough free time to relax.
For 1 I suggest a change of attitude and daily relaxation techniques+autosuggestion, for 2 I suggest daily relaxation techniques and doing something against the stress (more relaxed manner, or quit irrelevant jobs you might do weekday), for 3a) I suggest going to bed earlier, for 3b) I suggest daily relaxation techniques and more sleep.
