I get white outs all the time... My vision will go blurry and then everything will go white.. i will be very light headed, and have fainted a few times when the white outs have come... Sometimes my breathing is affected, but not always... Some are more severe than others... some last 2 seconds, some last up to a minute... I am not sure what they are... sugar seems to help them... I tend to eat a lot of candy... I am always sure to have candy in the car because my fear is to have a white out while driving
