[Lazuli]

I am convinced diet has an impact on my susceptibility as the only times I have ever blacked-out have been first thing in the morning on an empty stomach

1) after a night spent at high altitude
2) after a 2 min breath hold done before getting out of bed

I often feel faint when I have a low sugar intake, and my diet is rather saltfree (no pun intended!). I have upped my sugar and salt intake since the seizure and try to get a good breakfast in as I am quite prone to skipping food first thing in the morning. However, I have never experienced prodromal (pre-black out) symptoms from breath-holding before, only when run-down and low on water, sugar and salt.

I was also having amazing success with lowering my heart rate as part of my dry static routine. This may have aggravated the black-out as well.
