I have been so Tierd Lately! Help!?

What is going on...?
Lately I have been dragging pretty bad, I get about 6-7 Hours of sleep, drink plenty of water...eat the right foods but for some reason I feel like I am dragging especially when it comes to work...I have always been such a hard worker but it seems that whenever I step into the place where I work I instantly get tierd and don't want to do anything at all...I don't know what it could be...some people recommended that I need a change of job, what do you think it could be...

Let me add...I take vitamins every day and work out 5 nights a week...

well maybe you just have to find something you love to do. I think you might be bored of doing the same thing all of the time. Maybe you should start expanding your activites and see what happens. somtimes if you don't have the motivation to do somthing you will get tired and not feel like doing it. Try somthing new.
