I have just completed my first two oil pulls! I used sesame oil, and both times pulled for 10-15 minutes. However, I found that it made me feel really sick, and afterwards I get a headache and feel horrible for a while. My mouth also feels bad. I rinse and brush my teeth afterwards, as everyone has suggested. I was just looking back through some very old threads, and came accross an old discussion on Andreas Moritz suggesting to only pull for 3-4 minutes. I read a book of his once, and remember that too. Should we be pulling for a much shorter time? Could this be why I feel sick?
