For the last few days, I have felt like I have taken a strong pain pill. I have been dizzy, felt like I am really foggy. My pupils are dilated. Just sometimes, disorientated and have to make an effort to think straight. My mouth feels coated, my tongue and cheeks feel as though I burnt them. What could it be? I have NOT taken anything stronger than 500mg of Ibuprofen. I do feel a bit better after I eat, but then it all comes back.
