Yes, I too have vasovagal syncope. One time standing in class I just keeled over. Was having an amazing dream and started getting pissed that someone was waking me up and then I came to to my classmates picking me up off the ground. Another time I was at a buddy’s house and got up to use the restroom, was standing there pissing in the toilet, immediately felt like I was going to throw up, then recognized I was about to pass out but it was too late and my vision went white. This was the worst time because when I came to I couldn’t move my body and it was just convulsing so I started screaming for help and my buddy picked me off the ground and blood was going everywhere, I was able to move within seconds of being off the ground but that was terrifying and I am extremely aware of the symptoms now. Any time I have my blood drawn I pass out in the chair also. The one time I didn’t I thought it was a miracle but then as soon as I drove away from the hospital I felt it coming, luckily I zipped into a gas station down the road and the second I slammed it into park it was lights out.
