You may need to start slow. I started with a teaspoon and could only swish for 5 minutes.
I would stand over the trash can and cough up what I could. I slowly am up to a tablespoon of oil and and swishing 20 minutes! Plus I eat at least 1 tablespoon of oil before bedtime and I sleep great now.
Please explain what happened to you, if you don't mind. Others may have had the same thing happen.
