Hello hazn: I guess I don't really have any great suggestions for you. I just wanted to leave a note letting you know I read your post & I hope you can find a solution to your problem. I do think it probably has something to do with the time of year. I don't know what type of weather you have where you live. But where I live the weather is cold & dismal. It's dark by 4:30 in the afternoon. As a result I tend to feel pretty blah as well. But, then, at this point in my life, blah is pretty-much a normal state. So it's only more-so now by a matter of degrees.
