Anyone else ever just "always tired"

I work a shit shift pattern and its slowly getting to me, Like this morning I slept through 2 alarms and was late for work!


Could there be something wrong?


I can never get to sleep when I want to, an I've tried sleeping pills but I dont get on to well with them, ie: I either sleep to long on them, Or they just dont work! And I dont like the fact also that something is putting me to sleep


Any suggestions?
