No down, it is cerebral hypoxia. But not so severe to cause death or coma. I feel dizzy and lightheaded too, not only nauseous. I have had several falls bc of this. I also experience confusion, memory loss and cognitive problems and disorientation and uncoordinated movement from time to time.
Moreover I have an ac in my room. So it is not bc of the heat. Also I.have been taking the same psych meds for a long time now. So the meds can't be responsible.
