I agree that if you're not on sleep medication already, you may want to consider looking into this. If I didn't take certain bedtime medication now (trazadone, Xanax and saphris), my sleep would really suffer. On those meds, I feel well rested after about 7 hours of sleep (with a brief interruption or two).

Please don't feel guilty for having a problem with something that is very crucial to your wellbeing and functioning - - sleep! Lots of people struggle with it. You could always just go into work, and if it seems to be too much, you can always go home. Is that an option? At least you would have given it a go, and maybe that would ease your guilt some.
