When you feel so tired, but you cant sleep...

Never ever take leave after a 24hr guard duty.. Cos u will waste that leave.. Came back this morning from guard duty, was super shagged.. And i tried to sleep but just couldnt fall asleep.. That's like the worst feeling, tired but unable to sleep.. Decided to have lunch first and try again after that.. It worked and i've slept for 3hrs?? i guess.. Now it's 3pm and half the day is gone and still feeling the effects of the guard duty.. Not that it's a lesson learnt for me, cos obviously i cant control my leave now.. Just needed to make obvious how stupid the army can be to us.. Said enuf already..
