Anyone with SAD: Have you tried a dawn simulator (or sunrise alarm as I think they're also called)?

Hi!

So recently I've realized that I might have SAD. Round the winter solstice, there's about 6 hours of sunlight per day in Estonia and for much of December and early to mid January, it was also overcast so even the 6 hours of "sunlight" were kinda dark.

So I went to read Wikipedia and:

Two methods of light therapy, bright light and dawn simulation, have similar success rates in the treatment of SAD

So I'm just wondering if anyone has personal experiences with these, particularly the dawn simulation as I believe that's something I could just set up and forget hopefully (I have ADHD, I do NOT do well with things I have to repeat every day). Does it help? Do you use it outside of wintertime too?
