I think if it were me I would go down to 1/4 or even 1/8 teaspoon first and see what happens. Maybe try a natural diuretic like dandelion root if the bloat gets too bad.
I started salt supplementing before I started Iodine and I remember having some bloating for the first few days but my body adapted. ((Hope yours does too))
I have had some emotions/memories come up too. I don't have great advice because they still come and it is uncomfortable. Lets both try to be gentle and forgiving with our selves... and hope it clears soon.
