Sorry to hear this, and especially about the strange mood. How are you taking coconut oil? I love it so use it for all my uses of oil/fat, but maybe if you fry with it you won't notice the taste so much? Yes, it is really challenging to be experimenting blindly (in the sense that we don't know what's happening in our bodies) and especially with brain fog. I find it very frustrating. If I could afford it I would be monitoring my physiological state regularly to see if things are doing what they should, whether I need to change doses and other things, but all I can monitor is blood pressure, blood glucose and how things look and feel.
