Yes! This happened to me the three times I ate carbs. Once was peanut butter cups on Halloween, the other on peanuts and today I had what I think was my first migraine and I was crying and desperate and spotted an apple and had a few bites (I hate apples anyway).
All three times I got aches and extremely tired. I think my body was basically telling me I was poisoning it and teaching me a lesson.
Have you tried less sugary carby things with the same effect? Or without gluten?
I don’t think I was kicked out of ketosis, or that it is a result of that, I think it’s some inflammatory response in my body.
