I got the same info from Dr. Wright's books. I had the distinct impression back then that Lugol's was available only by prescription. If it was available only by prescription, I don't know when that changed. Without the internet to check things out, I remember haunting health food stores, hoping to find iodine I could use. Did the usual kelp thing, and that was all I could find. I was electrified the first time I read about Iodoral, and that I could buy it myself. After that, I found out I could have used Lugol's sometime earlier, but I never knew.
