Hi. I have diabetes. A couple times a year, I get sweaty, dizzy and nauseated to the point I have to go home, lie down with a cold wash cloth and sleep for a couple hours. (Usually happens after I eat something) I am not sure what causes this. I do get motion sickness very easy. Since I cannot narrow down what brings this on or when it is going to happen, I am not sure if I should be concerned. What is your opinion?
