My husband and I have been taking between 4 and 8 drops of Lugol's a day. We are both noticing fatigue. Is this typical in the beginning? I'm not planning to go beyond 8 drops until I see Dr. Brownstein in April. I have not had the energy to work out, so I'm in a bit of a vicious cycle with that right now, since the lack of exercise isn't helping the situation, either. All day I feel like I need a nap, but by bedtime I'm not sleepy, though insomnia has been a long term problem for me. My husband has no problem sleeping anytime, anywhere. He can zonk within half hour of a double espresso.
