Re: What should l do now....

Loads of vitamin C
Green powder aka wheat or barley grass
licorice root for your adrenals; I bet they have a hard time.
Continue salt loading
Dont do to many things at once, keep it simple; digestion before anything.

You may have to go through a rough phase; mine lasted 2-3 months. I know it is hard, but somethimes it is no way around it.
Backing off is one option, but you may choose to actually double the iodine; Trapper here had an idea that 100 + mg make the detox faster and easier than 50 mg or under. Sounds crazy, but it worked for me.
