As people said already, it's probably a die-off reaction. You probably want to cut back a little on the oil pulling, as already suggested. I've had quite severe die-off reactions, and that was my body telling me I was going too fast. I would strongly suggest taking Epsom Salt
baths (within moderation). That's probably the cheapest and most accessible detox assist you'll find. They really do make a big difference. My eyes are visibly brighter and my face less puffy after an Epsom Salt
bath. If you're really in a crisis, you can take some activated charcoal to help pull out the toxins.
