I don't have answers to the exposure questions at this time. We were only it in for maybe 48 -72 hours at a time once a month. I do know lead was not the only toxin found in the room, which used to be a rifle range, but it was the most abundant. We were exposed as recently as 4 days prior to my seizure. I know it'll be impossible to prove the link to that particular setup but if somehow lead is the cause, I can sleep easy and avoid contact in the future, which is my ultimate goal. So far , every other single test on seizures is coming back perfectly normal, even stress tests. I just want an answer and this honestly to me, makes logical sense based on the above
