@joegrane, thanks for the suggestion. It's not really a metal taste though, it's this really noticeable cold sensation, also sometimes a kind of prickly sensation on the back of my throat and tongue. I don't know if it's a damaged nerve or what.
I have been going to an ND, and among other things, he says I have some adrenal and gut issues.
Also, I wake up with these bad sinus and head feelings, sometimes weird dreams.
per "Sounds most likely dental-have you ever seen a biological dentist?
Do you have root canals or fillings? Any trauma to the mouth?"
I have 3-5 Amalgam fillings, 1 or 2 porcelain fillings, never had a root canal.
Mouth trauma - I've had a few. Once, about 28 years ago, as kid I flew off a moped, and landed on my face and shoulder.
I've been going to the gym, working out, then to the sauna, hoping the heat will stop and remove this bad stuff and I also hike once or twice a week.
I used to have a zapper, per Hilda Clarke's book, but it's not working very well. It may be broken.
I also think it's papers, my notes, I think there's something on them. May sound weird, but I think that has a lot to do with what is going on. I am trying to convert them into digital format.
I also run 2 air purifiers, seems like a lot... thanks again, still open to solutions.
