Since burnt things, like burnt toast, are in the same Bismuth family of elements, as melatonin, you can smell it, as it leaves the body…
What makes melatonin or burnt toast leave the body?

Extending your daylight hours, getting more light…Electricity can do it too…

Notice they mention coffee roasting as a smell prior to seizure (if you went to the link above?)
When you roast coffee, you get Bismuth at the edges of the bean…Bismuth, is like melatonin, is like burnt toast, charcoal, soot, ash…Same family of things…
if you lessen exposure to darkness, & greaten exposure to light, you will cause the exit of Bismuth family things out of your brain…
As Bismuth exits, you may smell it…Leaving…
Lowering melatonin/Bismuth levels radically can trigger a seizure…
Conversely, raising melatonin Bismuth levels can prevent one, slow one down, or stop one…
Staying in darkness longer will help people prone to epilepsy…
Fluorine is opposite to melatonin Bismuth burnt toast ash soot charcoal…
Avoid Fluorine is you have seizure disorders…
Soot or ash from a burning wood fire is good for people with epilepsy…Be sure to have a fire burning in the fireplace…
