You know something's wrong when...

You cannot sleep well at night. It's been almost two weeks since I found myself waking up at 3am in the morning and totally clueless about anything. The other day I overslept in front of the TV after dinnner for several hours and woke up thinking that it was already the next day and that I was late for work (cuz the clock was showing 9pm). Something is wrong with my body clock. My friends would probably argue that it is a jetlag. Since I had been away for a month then maybe it would take me the same period before I could return to my old rhythm. I would say my mind is thinking hard about something. Something undone. At this point, I'd die to get a good night sleep. Any suggestions?
