There isn't a drug we can stop or start to get rid of this problem. The only way to get rid of this problem is to find out what was the change they made in the panel tech some 7 years ago and circumvent that. = Make truly flicker free displays.
They think that PWM at 2.5Khz or more is problem free - it absolutely is not. When I use my Motorola G100 and set the brightness from 65% to 64%, my eyes get bloodshot within 30 minutes and the PMW is around 2.5Khz. Otherwise I can use the phone for reading books or playing games or what ever trough the night and day if I want, without getting any problems.
I never used a drug, so there is nothing to quit or any drug that would have caused my sensitivity to flicker, as I have had this most likely always, but like I said, the first time I noticed it was the Sony Trinitron TV. Normal CRT TV's were fine.
Also it does not make any sense to start taking some drug for the rest of our lives to bear bad display technology. We NEED to find out the source. PWM is very clear source for most, but unfortunately for many others like myself, it is the suspected temporal dithering.
My current belief is that they made some pretty universal change in LCD technology. Why I think so?
Because when I connect any offending laptop to my HPZR2740 display, it produces no eye strain like my desktop with Geforce 970 does not.
Because LCD projectors were fine 10 years ago, as they obviously do not have PWM and did not have temporal dithering back then. Now also LCD projectors have the same suspected Temporal dithering and it does not matter if I connect the projector to my GeForce 970, it still causes same eye strain as any modern laptop.
Because Surface Pro 2 had a bad color quality display and did not produce any eye strain when 100% brightness when there was no PWM, (Same with Pro 3, but I never owned it or tested it long enough to be absolutely sure). Pro 4 onwards the colors were great and so was the eye strain.
Because I have tested countles phones and laptops with Oscilloscope confirmed no PWM displays, but they still produce the same eye strain, but do not when connected to my HP display.
So while I do understand that my case does not represent everybody else's case, this is what is seen in many other forums, so I will make the assumption that the most COMMON scenario is eye strain due to flicker. PWM is flicker, Temporal dithering is flicker.
