Same here
But I am curious to know now 
That is a bummer, because I am most active after dark. That is when my son sleeps and I get to sew or knit, for which I need some artificial light.
I don't notice any negative effects from it though...or maybe I am just oblivious to it? ^^
Suiren, what I read i the forums, you do have a lot of health-complications still?
Often we do not get immediate "pain" from things we do wrong. It goes very slowly in the wrong direction and destroys or hormone-panels and glands gradually. It is not only food that matters. Light cycles matters as much and also seasonal temperatures. Nature is as it is for a reason... Or why are we aiming to eat our food in as a natural state as possible after all?
Adora, oil lamps are a very nice option! I have not used any candles still, and I guess I need them in one month maybe, but then I will do oil-lamps! They do not smoke the same way eather! Cool.
I have not much time for internet, it is summer still.
I was visiting my doc and Thursday I will get blood drawn for a lots of different things.
I will measure;
Testosterone
Progesterone
Estradiol
DHEA
Vit D
Vit B12 (because of parasites - if it less the I know I might have an issue, it was very good last year)
Cholesterol
CRP
and the regular bloodwork they always do.
This will all be scientific because I will do the same labs in spring. No guessing here, I want to test that is the only way to really know how something is working.
I wish more members would do this and post their results (many thanks to Lex and Sabertooth any other member who go this path too), it could be a very scientific forum then and so much countable! It will cost a little, but I think it is so much worth it!
