Yeah Ceti, I went from 1/64, to 1/32, to 1/16, then to 1/8. All for a month but then only 1/8 for about two weeks. I must have realized that I was getting too much iodine. I then tapered back down to 1/64 and almost got a goiter, but I believe it was diet related too. Then I bumped back to 1/32 for a week and then tapered off with kelp. I then found out about ray peat who designed a diet to optimize thyroid function. I'm doing great without the PI nor much kelp, other than some kelp in sushi and the fish I eat. I'm keeping up my natural sulfur intake from palm sugar, sulfur is rumored to keep the brain clean. Awesome dreams every night, tons of deja vu. The dreams are so vivid that I consider them experiences more than dreams. Nonetheless still awesome and cool. And I always wear PIneal symbolism (black with red/orange on the inside). Red/orange is copper, the pineal organ, and black is carbon, the cerebral cortex. When copper rubs on carbon it creates electricity, this is what creates energy for our body. Thanks for your help in cleaning out my brain, but I did almost get a very bad reaction from coming off the iodine too quickly. I don't think going from 1/8 to 1/64 is a good idea. Maybe tapering slower would be better. I also think kelp is a valuable tapering agent.
