I found this out because I tried ss last year and the same happened to me. This time tho with the left over cd meals, the weekend before I started CD again... I added the cd meals to my usual food to get used to them again.. I had the exact same head rushes and dizziness which is why i know it's the sudden wack of nutrients etc.... it really helped me to know this as if we think it's to do with hunger then we worry xxx
