I don't like it either when it gets dark so early. I have a daily routine which includes an evening walk with my dogs around sunset and I really enjoy that walk. When the sun starts setting at 4.30 in the afternoon, it does not fit in with my schedule at all!!!! I am lucky though in that we do tend to get a lot of sunny days here even in winter. It's just that the days are very short.
I'm really glad you have your SAD lamp (((((((((Beth))))))))))))) because I know you've said that helps you.
Hugs to all

and warm, sunny feelings!
