Yes! This is a great thing, I think you will like it. For me, the time of day when I use it is very important.
My habit in the very dark of winter is to turn on the light box first thing upon waking. It is set up next to my computer and reading area, & it's so easy to wile away 20-30 minutes reading the news, having a cup of coffee, while getting my dose of sunlight. And I don't feel like I'm "wasting time" fooling around on the computer. I'm getting my sun!
It's like having one more tool in your arsenal to help yourself. Can't hurt, right?!
