Yes I had similar issues but following Dr Cywes' advice messed me up even more. Professor Tim Noakes, his mentor and also a South African who taught him about low carb, disagrees with him.

But I'm not here to try convince you. Rather to show people that this issue is not black and white one way or the other, but more nuanced. I think it would be much simpler if we're weren't all messed up by our modern toxic environments. It seems to make us all sensitive to different things which cause various physical and mental issues.
