Hello, my name is Jake. I like going to concerts and im planning on going to Bonnaroo this summer. Ive attended outdoor summer concerts and other events such as carowinds. From time to time when at these events I get rapidly out of nowhere dizzy, feel extremely faint, and on occasion my vision starts to go all white. I drink alot of water but it still happens. I dont know if its a combination of the heat and the standing up for long periods but im usually one of the only ones around it happens to. Im a 24 year old male weighing 160 and at 5'11. I have no known medical issues. I really wanna enjoy myself this summer but I need answers. If you have any insight I would greatly appreciate it. Thanks
