When it comes to FBD Lugols is the bomb. I had severe FBD, large lumps and very painful. Now, after 5 months on Iodine (lugols) I have about 8 very small , rice bubble size lumps left. All the large painful lumps have completely gone, and the little ones are getting smaller and smaller by the day. Its sooooo wonderful to feel normal again, and to have no pain. I can't tell you what it means to have normal lump free breasts after years of pain. I started with 100mg per day (16 drops) and I am now down to 50mg per day (8 drops) and will probably remain on this dose indefinitely. I have 2 friends that experienced the same relief from FBD, they started Iodine supps when they saw what a difference it made to me.
