sten,
You might want to look at this, a way to get some vitamin D without sunlight:
http://products.mercola.com/cod-liver-fish-oil/
“I recommend fish oils/cod liver oil as an addition to the diet of almost anybody of any age... fish oil for those in very sunny climates and during summer, and cod liver oil containing vitamins D and A for almost everyone from fall through late spring. Think of cod liver oil as “fish-plus” — fish oils plus vitamins D and A.”
It might help your deficiency.
Hopefully, you’ll get this before the gestapo takes it down.
Thanks.
