Thinking about getting a light box that simulates dawn to combat how bad I feel in the winter months. But they are so expensive I don't want to invest before doing some research among other users.
Not sure if this is relevant, but I have problems sleeping at any season, usually waking between 2 to 5 times a night between 11pm and 7am. Typically stay up for 15 minutes to an hour for each of these wakings. Needless to say, I find myself getting fairly drowsy at work in the afternoon.
Even after 6+ years here in UK, I have not acclimated to the 4:30pm dark. All my life in Virginia I had extra hour of light in the winter. Also have to say that I now dread the reduction of daylight hours so that I start feeling low before the clocks change in October.
