I found these accounts (see links below) when going over some old issues of the Journal of Borderland Research. It reminded me eerily of your DOR experience.

Also: I've read/seen on youtube about people taking (accidentaly or unwittingly) some high doses of chlorine dioxide. One took about 37 drops the very first time he tried it out (a friend of him recommended taking chlorine dioxide, but the dosage apparently got lost in translation...). He had a fever and cold shivering throughout the night, but in the morning he was feeling very well. The other accidentally inhaled a bit too much of the gas (while making some CDL at home), and had some enormous mucous discharges and coughing for several hours (or also through the night, I don't remember exactly). But after that, he was also quite well.

The MWO mentioned below is the Lakhovsky Multiwave Oscillator. A pdf about the MWO (also from Borderland Sciences) can be found here:
