Hi I appreciate your thoughts on this. I have it for hours and I think it is something else. I have very sensitive smell senses. But I think it is something is triggering it or a brain/med chemistry is going on. Had it off an on for two months.
I just know it is foul and unpleasent. Never had this before in the 37 years I have had seizures. So it is odd and kinda unexplainable.
Will go to link you gave.

Thanks, Cedar
