At risk of repeating myself, the reason I posted is to alert people.
Because those people who ARE affected may then come to realize it.
I.E. some people own worse monitors than others do (no matter whether CRT or LCD).
If they feel it they'll realize it just by dint of experimenting with avoidance & then seeing how they feel during the period of abstention.
It's as simple as that.
Ditto re: Vitamin C, etc. etc.
Believe me, I'm not trying to "market" anything.
This isn't a "religion" or fad or product. This is just information that I'm sharing for no other reason than to prevent others from the pitfalls I've bitterly experienced.
