hillie1971 : I am 3 and a half years. I don't want to spook you but hey it is halloween time.

Yes symptoms keep changing on a daily basis and some times hourly basis Doesn't matter if I overdo/underdo or do nothing. I just gave up on finding triggers and has some workarounds.

I had metallic taste but that was because I had olfactory damage (both smell and taste) and did have that metallic taste for some time. It improved a lot though after 2 years. I remember all ENT specialists asking whether I had metallic taste on back of the throat. May be you can check up with them. I assume you have no smell disorder.
