31 years on thyroid meds, want off!

I'm new to this forum..been reading, but need to ask some questions..I'm sure things already discussed. I've been on thyroid meds for 31 years, I currently take armour 120 mgs. 1 tablet per day. I am hypothyroid with a goiter.

I found iron 4 years ago..the supplement saved my life I feel, I took it for a year, then I found raw foods, and I lost 71 lbs.,now I'm doing a parasite and worm cleanse, and I want to start taking Lugols iodine. I'm afraid though, I would hate to lose my hair and gain 25 lbs.

If I understand correctly, I can take the Lugols while taking the Armour, and hopefully reduce the armour until I'm weaned off. Do you continue taking Lugols and do you ever get off of that?

Thanks
