Hashimoto's disease
"Started Naturethroid after seven years on Levoxyl and Cytomel, with unrelenting fatigue, migraines, constipation, and feeling cold all the time. Initially felt great on the Naturethroid. But after two weeks, started to have headaches again. Then developed diarrhea that lasted for two weeks. It was a nightmare. Went off of it and went back to the synthetics. So disappointed that it caused this reaction. These natural meds are not necessarily the perfect solution that they are portrayed to be, even if they do work for some."
