Been swishing everyday for about an hour to start the day for 2 1/2 weeks. At first all of my pulls would come out white and foamy. For the past week the last pull has been looking pretty much the same as when I put it in, and now it's starting to happen with my first pull. It's not perfectly clear just yet, but it is progress. I'm using the same oil for the same time and seeing huge changes in the consistency of the spit. Thought I'd share.
