I was fine over the summer, but at 55.6° north in Copenhagen, sunset is now 15:53. That makes it more difficult to find daylight-time outside on a working day, and the city is in winter mood (fewer people wandering outside in the evening) so it feels more lonely.
I changed the light in my office from a normal (for home), "warm" bulb to a 1500lm 6300K "daylight" one, which helps. It no longer feels like I ought to be relaxing at 15:45.
I'm also going to make more effort to just cycle or walk around outside over lunchtime. Both things were easier when working at the office -- it felt like a "work" place with bright lights and big windows, and I couldn't avoid the outside-time to get there.
I highly recommend a smart bulb that can change color, for example Philips Hue White Ambiance. You can even set it to automatically fade from daylight to warm at a time you specify.
