That depends on your diet and power of digestion....
If you have no virtical line running down your tounge ( having one indicates faulty digestion ) if you have no white creases in the nails ( these indicate lack of calcium and or zinc absorption ) and you get hungrey on a regular cycle without experiencing digestive complaints ( gas, bloating diareahha ect ) then you will do better even if not taking cofactors. But they are still recommended.
The symptoms you describe sound like mental confusion which could be bromine induced.
Your hobby is a good test scenario to see how bad the confusion is.
Drink enough water and lower the Iodine dose if your side effects become unbearable.
