For me what helped is
1) Sleep on the back ie not to the sides
2) Tell yourself a person needs only 8 hours of sleep.
3) Do not sleep excessively though, can make u more tired
4) I stopped drinking coffee and tea
5) Eating healthier.
If your job is too un challening, take up an activiy that interests
u. U will look forward to the end of the work day, and feel less
tired during the day.
If your job is too challenging, than it could be the problem.
