Is it not good if you start oil pulling for about 3 weeks and then stop for like a week? Will the benefits be lost? Reason I ask is because my oil recently went rancid and I haven't had a chance to buy another yet. I did try Olive oil in the mean time, but it doesn't turn white, even after 20 minutes, it also felt too thick and hard to hold in. So I'm not using it anymore. But would I have to start over completely (new side effects) or would a week of missing it matter much? Thanks!!
