You'll get used to it. Eastern Europe has relatively early sunsets, in December as early as 3.30PM. A friend of mine moved there for a couple of months and said that while it was weird, she got used to it after a while. But with DST, every half year it's a mess of switching hours and you have to get used to it again and again and again...
That is insanely early. I can deal with 5pm, but 330pm is something else. When I was studying in France it screwed me up when sunset was happening at 10:00pm. That was super late, but awesome at the same time.
When I'm home in Canada for christmas, sunset happens around 4:30, so I'm familiar with the concept. DST is definitely bullshit. I just have a problem with the two gigantic time zones, and see them as impractical. Lots of pain for relatively little gain, as it were.
