If you are chronically sleep
deprived, it's essential to find out why.
If it's due to long hours at work or play, that needs to be dealt with. If you are simply unable to sleep, see your doctor to discuss what the issues may be. If you are falling asleep the moment you hit the pillow, you are sleep deprived. And you can't "make it up" on weekends. Good sleep will make you feel good during the day.
