I am aware of one other person that had a somewhat similar reaction. I have no idea what is going on.
The solution you mixed up has about 6 PPM available chlorine dioxide. Solutions with a higher concentration than that are being used with birds and both salt and fresh water fish without any problems. You would think that it would be easier to make birds and fish sick, but that doesn't seem to be what is going on here.
I would suggest that you limit your use to topical applications and find something else to drink.
