Helo Tmoeono, thanks for your question. I think the better choice is eat at 8 pm, during your pause, a meal rich in carbohydrates, easly to digest, taht gives you energy. If you can you can take some energetic snack after dinner, to support you during work.
Before bedtime take a light snack (yogurt or a fruit).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
