One time we were looking at a pool table to buy and the store had the door open and no ac. I didn't drink any water that day and we were just sitting there and all of a sudden my hearing was going in and out. Then it came back and I got very light headed and such. After that I was very dizzy and black splotches started to appear and I couldn't see. All of a sudden I stumbled, by dad looked back, and I was on the ground. Next think I know I am in the car throwing up and completely forgot what happened.
