It took me weeks to take the plunge.

My biggest concern was tipping into mania...because light therapy can do that to people. But that takes time, so I felt I could catch myself before it was
"too late"

My feelings are very much seasonal too. I can't really extrapolate to someone
who is really clinically depressed compared to SAD people.

In the end, the guarantee (30 day no questions asked) did it for me.

But just to reset sleeping patterns, so your body can take over and help with healing...that is something this light is good for. This was my biggest and very obvious problem!

To me it is a better solution than oral drugs.

I hit a sleep plateau after the first week or so. But the excess sleeping has really been improved now. I would guess that it takes time to biochemically
change things. Especially when systems are sluggish or not used to functioning. I also think B6 is very critical for it all to work, since B6 is required for serotonin manufacture.

I am not trying to "sell" the light therapy...but I think some people could
benefit. You sort of have to "feel" it is right for you.
