As the infusion progressed, I continued speaking to the medical scientists. I told them about my passing through the cocoon and the river, but then I completely left my body and speech was no longer possible. I existed within an omnipresent white light and heard/thought, "This is why you came here. The moment is now." An invisible switch flipped, and the voice continued, "It is done. It worked."
I felt nauseated and tired for the rest of the day, but the next day, I felt great. Normally, in the afternoon, I am so tired that I can barely think, and doing my I.T. job is difficult, but that day, I was marching up and down the stairwell during breaks, to release my energy. The energy boost faded in subsequent days, but there was a more lasting effect.
Ever since my infusion four months ago, the pain from my plantar fasciitis, achilles tendinitis and rotator cuff tendinitis has been reduced to less than half of its previous level. I had seen multiple doctors, gotten many scans and tried multiple kinds of therapy for those problems. The pains are still there, but now, I rarely think about them, and they don't stop me from doing anything.
I didn't expect this effect, and I can't explain it. I know Ketamine is used to treat depression, and there is a large correlation between depression and chronic pain. I didn't think I was depressed. Whatever the mechanism, I am pleased with the result.
