Thanks again - saw a lot of diff. kinds of N-I salt - no idea what's in any of them, but pure sea salt should be good (got some for Xmas one year - sis-in-law's very 'natural') so may look for it again now. Think I need to relax and get a decent routine going... funny thing is I've responded to his all-day whines a lot, but he def. still has his 'old routine' clock in his head so even if I've just fed him 20 mins ago, when it's time, it's time! Sheesh!This is from Goodrx - which is to say, sodium chloride is what you're looking for without any other ingredients.
What is Noniodized salt?
Non-iodized salt is often purely sodium chloride (think sea salt). This salt comes straight from the sea or underground salt deposits. Depending on the manufacturer, some non-iodized salts may be processed to create a finer texture, and may be mixed with other ingredients.
