Re: afib, weight gain, blurred vision
What could have happened is that
Iodine has temporarily triggered the hypo T = weight gain.
Blurred vision is more an adrenal fatigue symptom, not so much bromide as I see it.
Iodine can, especially when taken without its companions worsen adrenal fatigue.
The adrenals need salt, vit c and b, I also used licorice root for a year.

Iodine also highlights any deficiencies you may have.
Salt is vital in the protocol, as it both helps the adrenals and helps the bromide detox.
From my own experience, saltloading helped the palpitations I used to have when I was hypo T.
Please update after a couple of weeks on real salt; will be interresting to see what happens.
I prefer the himalayan salt, others use celtic or redmonds.
