I'll tell you a little secret. I don't really watch the "foamy" thing that much. In fact, after doing OP for about one year, I don't pay attention to what happens to the oil at all. Others are much more intent on the pulling actions happening in their mouths.
I pull for 20 minutes every morning, and perhaps for 20 minutes before dinner. Lately I've pulled with pretty heavy oils that don't really foam up at all.
Right now, for the first time ever, I'm doing back to back pulls, first with Pine Needle Oil and the second with coconut oil (first time ever too) . I want to see the color purple like Trapper LOL!
At first my oil gets thick, and then it thins out, and it's different every single day, and different will every different type of oil.
If I were to give you a piece of advice, at least pull until it gets thin. If it stays thin, pull for 20 minutes anyway.
Keep Swishing!!
