I have been having brain fog for like 3 months now. Initially it was not significant but now it is slowly hampering my daily life. I have vitamin d deficiency and for that m taking kalzin solution every week (60000 i.u) approaching nearby things are getting worse. Right now m trying water therapy for the gas and kidney stones problem. But for brain fog i have no clue what to do... Internet suggests lifestyle changes like sleeping regularly on time, eating healthy and getting exercise etc. I just want to know the procedure to tackle this problem and be brain fog free once and for all of course the natural way with no medications.
