question: Hi doctor, I am suffering from severe brain fog to the point where I cannot leave the house or go to work. I also have a dull, numb feeling on the top of my head. It almost feels like not enough blood is going to my brain. I have a feeling of derealization constantly. I have suffered from a feeling of derealization since I was about 15 years old but only in the last two years has it become debilitating. I have tried adding Potassium, Magnesium, Sea salt, B vitamins to my diet but nothing has worked. I am now trying the gluten diet and I am on day one. When I was 18 I took Ecstasy tablets most weekends for one year. But I have not taken them since then. I am 32 years old, 83 kg in weight, 5 feet 10 inches in height.
