Yes....I do and I think it is from allergies....It doesn't seem that most doctors know how to cure this one. I think my allergies are related to my pituitary problem and that once I get my hormones up to the right levels, things should be better. Brain fog is a tricky one. One doctor I spoke with suggested a product with Interferon and Interlukin in it that is also homeopathic. The company is Guna. You can only get it from a doctor. Might be worth a try.
Hi danabarb! Yes, i have this same thing happen from time to time when my allergies are acting up. In fact it's going on with me right now. I get this spaced-out feeling and it's so hard to concentrate. Hope you feel better soon.
