35+6  and I just can't stay awake during the day. I have a desk job and I literally have to fight falling asleep. I completely gave up on coffee because I would find myself falling asleep AFTER drinking a cup. I get enough rest. I stand up and move often but I just dunno what else to do. Should I just go on leave and rest up for the next month or are there any suggestions to fight the exhaustion?? Please help.
