Question about seaweed, iodine (deficiency and overconsumption), and thyroid changes

I recently decided to make sushi for the first time, and along with that, re-discovered my love of snacking on plain nori (my parents were health nuts as a child, and as a result my favorite snack as a kid was snacking on sheets of nori. weird i know).
I haven't snacked on nori sheets since being a kid, but am finding again that I love the taste, texture, and idea of snacking on something "healthy" and very low calorie. But the package of nori said that one sheet contained about 90% of the daily recommended allowance of iodine.
But I also noticed that within a couple of days of my nori-snacking, my mood began to improve. I started feeling better, more energetic, and hopeful, when nothing else really changed. My guess is that my thyroid was functioning low prior, and the iodine > thyroid > mood link revved it up.
I generally eat quite conscientiously - eat my fruits and veggies, lean meats on occasion (once, maybe twice a week), I cook and don't eat out very often. We do have iodized salt in the house, but I don't use it often and only salt dishes to the point of necessity (I salt occasionally when cooking, hardly ever on the plate). And I kind of forgot about iodine in the list of necessary vitamins and minerals, so I think my diet was unconsciously lacking in iodine.
Anyway. At what levels would too much iodine be? At what point does iodine consumption become risky and dangerous, leading to thyroid complications (and cancer!)? Should I cut back and re-introduce increased iodine much more gradually?
I like nori and would eat more if I didn't think it would be dangerous. How much nori would be too much?
