Don't like the oxygen poisoning and burning feling in my lungs when breathing pure oxygen.

Astronauts on space suits often breath pure oxygen. The thing here is the absolute pressure of oxygen, not partial pressure, if every other gas on the atmosphere besides oxygen disappeared you would breathe just fine before dying as the weather goes haywire.
