I cant help you but I can relate...I wasnt sure what was causing it but it's been getting worse, it seems to be after i eat to.
This intense fog an pressure, like something is squeezing my brain. I cant think I feel extremely drunk. Then as it starts to clear I start to get a headache. All i've eaten today is chicken and a bunch of pecans. SO maybe the pecans caused it not sure.
Its really annoying, an affects me horribly. I've never chelated but I did do a challenge urine test with DMSA a couple months ago.
