Here's an update. My low-processed sugar diet has resulted in me bounding around full of energy, but the rebel forehead spots still refuse to shift camp.
I've gradually reduced one food item or the other to try and identify what is it that is causing these spots and I've finally figured out what it is. It's food. Food gives me spots. If I cut out Food from my diet, I should be spot-free. Yes!!
(Mum, I'm joking)
