Hey Lecarpeton is your SD still, miraculously, gone?
Not Lecarpeton, but mine gone by supplementing 400 mg of elemental Magnesium and 1 liter of orange juice daily.
Before that I barely got any vitamin c and of course I was Magnesium deficient since I used to have lot of cramping legs at night.
I had SD for decades, I think dropping PUFAs had some impact too.
