Wow am kind of impressed your pdoc recommended it. I thought it was a kind of crazy alternative thing as my brother is very off grid.

I have been keeping my light box on for hours. It's off to the side of my working space. I turn it away so it isn't directly shining in my face.

I do have a rather dark apartment and that's why my brother sent it to me. It really seems to be helping me. I don't get enough direct sunlight due to lack of plentiful windows and a not so great northern exposure. Everything about my apartment is good except the light situation which has now become a deal breaker. I won't be resigning my lease.
