I had the shaking’s too and for me it was the reaction of my nervous system do to malnutrition and overflow.
What made me react to your post is that you wrote you have diarrhoea. Do you know that you have for sure Candida?
I believed I had Candida and struggled with different diets for over a year, the last 2.5 month where spend with the diet here on the forum. I suffered like you from diarrhoea and brain fog, loss of about 30kg, wind, stomach pain, rectal itching, anxiety, internal vibration, panic attacks etc.
First I found that EFT Tapping was a great help to calm down the shaking’s and panic attacks. Second I figured out that I didn’t have candida but IBS. That particular diarrhoea form of IBS is cured only with a low fibre diet and I stopped with the diet here.
Today I am totally healed, I eat everything but not much fibre.
all the best
