I don't know if you can count on symptomology to guess that mercury is being sprayed on us. I've suffered from MCS (Multiple Chemical Sensitivity) to a small degree most of my life and have gotten much more sensitive in the past 2-3 years. If I am in the room with a person who washes their clothes in a detergent like Tide, I get pretty much all the same symptoms you describe from chemtrails, including the nearly instant neurological symptoms. My eyes will start to itch and burn, my sinuses will get irritated, my chest will get tight, my mind will race and I will get extremely anxious, just to name a few symptoms. Even after the exposure has ended it will take a little while for my mind and body to get back to an equilibrium.

I've tried many supplements to remedy the MCS, but nothing really changed my reactions, so I'm counting on ALA chelation to fix it. Even though I am extremely sensitive to chemicals, I still do not notice a reaction to chemtrails, besides occasionally having a little more muscle ache.

I'm not saying that you aren't reacting to the chemtrails, I'm just saying that its a very far stretch to say chemtrails contain mercury based on the symptoms that you describe because I get nearly all those symptoms from things that certainly don't contain mercury.
