What did I have? Heat stroke possibly?

Well you ped out. The same thing happened to me when I was in an indoor consort at the Hollywood Palladium. Sadly some people are more prone to fainting than others. Sometimes people p out due to dehydration. So try to drink lots of water. Not everyone can handle heat I know it blows because I am the same way the water thing helps me so give it a try. Hope I helped.
