You say you were using a "rebreather mask". The type of mask needed for good relief is a non-rebreathing mask, which has a bag on it, and three one-way valves. This type of mask ensures that you are breathing only 100% pure oxygen. Is this the type you are using?
What flow rate are you using? If the above mask is used, a minimum 10 liters per minute will be needed. It is also important NOT to use a strap to attach the mask to your face, and to NOT lay down while using this type of mask, because if you should recover from the headache and fall asleep, and the oxygen tank runs empty, you could suffocate.
This method of using oxygen works very well. I have tried methods that allow air to mix with the oxygen, and have always been disappointed with the results.
