My 2rd longer DF

I am starting my 2rd longer dry fast today. My goal is 5+ days, depending on my biofeedback of course.

I read that dehydration runs the risk of a heart attack or a stroke. Does anyone know if/how blood pressure/pulse rate might give warning to an impending heart attack/stroke? If my blood pressure remains low and my pulse rate remains under 100, does that mean there is no risk for a heart attack/stroke?

Anyone else is fasting right now? Having a fasting buddy helps a lot in not considering "QUIT"...
