What are those repercussions?
I can't say for certain as I have no basis of experience outside of working nights only twice a week intermittently for the past year, but now that it's all I'll do, I'm concerned of anecdotal testimony of it being rather taxing on both mind and body. It's hard to refute that humans were better fitted for being diurnal rather than the former.
But on the bright side, it's a guaranteed 40 hours every week, I get an overnight and Sunday premium, and for the most part it is rather slow or outright stagnant late at night. Might be a good way to catch up on my reading. Been spoiled by Amazon's audio books.
