I'm so sorry you are experiencing all of this. You are like the proverbial "canary in the Oil mine".
Some people experience benefits quickly, some slowly, but I have yet to hear of anyone experiencing it at warp speed, which it sounds like you are indeed.
I guess we could all be alarmed at what is happening to you, but I'm just not. I believe that you are having an honest to goodness healing crisis, and very dramatically so.
On the other hand.....could you be allergic to oil? It's the only negative that I could come up with....! Do you ingest the oil you are swishing with regularly? Maybe changing to a different oil would have a different, and gentler effect?
You must keep us updated about how you are. There is no shame in quitting if you feel you need to.
