I'm not too sure, I've only had the metalic taste once when I took that pannic, I have heart burn every day and a couple of days now and. Then I wake up and feel all shaky and ill, I have a constant cold, and I'm pooing 3 times a day, I never used to do that, I used to poo once every few days, (sorry for too much info) my gums are sore. I got my blood taken the other day, waiting on results. I feel so crap its horrible. None of this is pregnant related, is it?
You need to get help from a doctor today. It sounds like you are going into what is called thyroid storm. It is a medical emergency. Your thyroid is in "hyperactive" mode secreting too much thyroid hormone and the rest of your body is trying to react and can't keep up.
Could you be pregnant? I got a nasty metalic taste for 2 months with my last baby...it was the worst thing in the world for me! I was always tired...passed out a couple of times! I was always thirsty! My heartburn was awful! And I had to pee ALL THE TIME! And I had a ton of discharge!
It could be environmental allergies ..caused by the aerial spraying, many are sick with similar allergic reactions, to check for toxins you could ask for a heavy metal toxicity test ..try taking some anti histimine see if that helps you ..good luck
i also notice that i have started getting loads of scabs on my scalp recently which are irratating :(
