My Dr suggested trying a lightbox over the winter. I suspect that I have had Seasonal Affective Disorder for several winters now, so Im willing to give it a try. The info I have says that light therapy can be useful for CFS, just wondering if anyone has tried it?Im going to rent a lighbox for a few months (�25 per month) to see if it makes any difference. Hopefully I'll perk up in time for Christmas!
