As a thought re. "blue lights", have a look at getting some "daylight" bulbs. They're available from B&Q, Homebase etc. now, and are made from a blue glass that apparently emulates daylight as opposed to artificial light. They're a bit duller than "normal" lightbulbs, so go for an 80 watt instead of a 60 if you can, but even if you get only the 60s you soon get used to the slightly duller light. I did find, though, that they helped my SAD quite a bit - and without forking out chuffloads on a lightbox. Many commiserations about SAD - it's a bugger, but it's doable in the end. One other suggestion - not for this year, but bear it in mind for next - is to take a break in Nov to somewhere sunny. That seems to "top up" the sun levels, and work pretty well...
