Is there such a thing as SAD ? I feel that i become more depressed and fed up in winter and has anyone used one of these SAD lamps and if so are they any good.If I thought that they would make the winter a better experience I would buy one.
There are 100s on the net and the manufacturers certainly give them good reviews and promise all sorts of health benefits but is this just a marketing ploy?

Anyone use them ? what type are best ?
