Dear Sir/Madam,
There is no need to double the dose of antibiotics because oil is naturally the strongest antibiotic. If you have an infection for a long time, then just drink oil because during a long infection, bacteria become resistant to regular antibiotics and you only poison yourself. You can try to inhale oil and in that case you should pour a few drops of oil into one half litre of boiling water, close your eyes and inhale several times, but be cautious! Increase the intake of raw fruits and vegetables to enhance your immune system.
Best regards
