Ok so I haven't pulled in almost a week. Saturday morning, I didn't eat breakfast until over a hour after waking. This isn't unusal for me. But I got the acid again. So I'm starting to think it's not neccesarily the oil pulling, though it certainly exacerabates it. It's more about having an empty stomach. My husband pointed out that I recently started taking Spirulina at night. Could that be the cause of this stomach acid?
