When I first started on Ev4, I really hated the addition of NB.
I felt like:
“Why @Fire, Why? Why would you do this to us? 
… And if you absolutely had to,
… Why not create an Iron Throne of Emperor - a V4 with No Healing? (masked obviously) 
… Let us have the Choice!”
It took me 3 weeks of stacking Ev3 with QL stages to prepare myself to run v4 without headaches.
Now, after 17 days, I’d say New Beginnings was worth it.
The direction I’m now taking my life was something I had never considered before. 
Full Disclosure:
Starting yesterday, I have resumed the Iron Patriot at Ev4:Ev3 at 2:1 ratio.
This has nothing to do with NB.
Ev4 made me polyphasic - I was sleeping 2-3 hours three times in a 24 hour period.
Ev3 normalizes this for me, along with providing higher levels of optimism & forum posting. 
Note that, even with the poor sleep, productivity was better on Ev4 solo.
