Yes, I stopped taking thyroid medication when I went raw. I had been on it for abt 13 years and was on a high dose - 150mcg daily. My homoeopath guided me to stop taking it and gave me homoeopathic remedies to use instead and I began to take a lot of kelp - around 1500mg a day, as pressed tablets. I took the remedies for around 6 months, then didn't need them anymore. My thyroid now supports itself just fine and is balanced with my raw lifestyle and the large amount of kelp and sea vegetables I use. :)
