I disagree, in my case. I am using Iodine to treat FBD, a potentially pre-cancerous state. reminder: around 90% of American women have FBD to one degree or another.
So I guess that I would disagree in most people's cases, especially women. We need more I than men, especially large-breasted women.
Io-supping has never made me sleepy. Definitely made me hyper for a while, early on.
