Kevin -
Please keep us posted on this! I'm sure you are on to something,
though if not a cure, then at least an effective "therapy."
I have far fewer SS episodes than most posters on this site (and so
far I haven't had the other face-related hallucinatory issues, nor do
I have the migraine/pain component - at least not yet) but I am
convinced that, at least for me, visual stimulus and overall fatigue,
both physical and mental, increase the likelihood of an SS event at
any given moment. MOST of my SS episodes happened in conjuction with
lack of sleep, during heavy computer use periods - i.e. eye strain,
and often with a memorable trigger - seeing something bright flash in
just the right spot where the SS expands from...
In other words, if you stay well rested, stick to your optical
prescriptions as much as possible, etc... and are lucky enough to
avoid accidental exposure to bright flashes (car side mirror passing
by at just the right angle, for example, or direct sunlight reflection
off water on a table or counter) then I suspect you will have far
fewer SS/CSD events.
But I HAVE had SS events when well rested and in (what I remember to
be) the absence of eye-strain and the normal bright-flash visual
trigger... sort of spontaneously - so I suggest that the rest and
mitigation of actual eye strain will dramatically LOWER the
probability of an SS event at any given moment. But I continue to
suspect that those of us who CAN have them (for whatever reasons) will
probably continue to do so, though at varying frequencies depending on
environment...
