My 20 year old daughter and she has been having fainting spells. She did this twice, when I tried to yell at her across the room she was not responsive. She also has Ehlers-Danlos syndrome. Preceding the fainting spell , she is usually getting up from the bed or couch....She is at University of Minnesota I actually staid with her last week and she fainted on Tuesday and Wednesday. When she was waking up she had a very strong craving fof sugar. She did do this at stressful times, she often vomits prior to fainting. I guess she may have panic attacks. She is as minor bipolar and tales 20 my of Prozac a day.
