Help Fasting for sodium nitrite

[LapisLazuli]

Hello everyone. I apologise if this question has already been asked ,but I couldn`t find any info on what Im going to ask.
So I need to be fasting for 4-8 h for sodium nitrite method to be more successful. But does sleeping counts as fasting in such scenario ?
For example if I sleep for 8 hours then am I good to go after waking up ?

I believe the main consideration is your metabolism. Does your stomach feel empty when you wake up? If you typically take 8 hours to metabolize food then 8 hours asleep (I'm pretty sure metabolism slows slightly when asleep) may not be enough. But at the end of the day it's better then nothing.
