I'm not sure what I have is a mild form of narcolepsy or what?
It started in Jr. high or high school. My mind would suddenly start racing seemingly unrelated thoughts and I would pass out for 10 minutes. Always 10 minutes. It wasn't sleep. So every time my mind uncontrollably start racing I'd rush to sit down. If anyone asked me if I was okay I'd just say I was really tired and fell asleep. I still have those moments but now my mind doesn't usually race. I just seem to nod off in a chair, on the toilet, standing up. At home, in public, when I'm stressed, when I'm relaxed, after eating, waiting along time to eat, when I'm cold or hot, when watching TV (usually can't finish watching a movie). Driving was a challenge. WAS because I stopped driving. Sometimes I figure it's because I didn't get enough sleep, but other times I would be wide awake and out I'd go. And now it could be anywhere from 10 minutes to 40 minutes. Is there any kind of tests I could do at-home?

I saw a video about a women who faints several times a day and she was diagnosed with postural orthostatic tachycardia syndrome, https://www.facebook.com/watch/?v=400310591205344

had tachycardia when I was heavier. It's when your heart beats too fast.
Did they ever solve her problem?
