The Science of Fasting

Went ahead and broke it. I was already feeling stressed (but not from not eating), so it felt better to just go ahead and stop letting hunger add to the stress. And nearly 36 hours is not a bad run for just getting back into it.

I'd prefer a short re-feeding window but it won't happen today. So I will attempt another [hopefully] 36 + starting after dinner tonight and ending some time on Thursday with a [hopefully] shorter re-feeding.

I keep saying "hopefully" because there are many factors besides willpower that enter into the length of a fast. For me, anything beyond 36 has always been tough (though, that's when you really start learning new things about the effects of a fast). But you have to keep listening to your body for a signal that it may be time to break and then re-start again.
