"And sometimes longer".
Autophagy is a self eating process that happens when you starve yourself, it doesnt happen naturally you have to make an effort. Personally i have benefited from fasting and ketogenic diet.
"one day starvation diet" recently won the nobel price for autophagy, i dont remember his name but he recommends healthy people to eat maximum two times per day.
they clearly states that the drug finds its way in, and gets stuck there folded in by other proteins.
i personally have a hard time believeing that a drug can give you symptoms after its out of your system. But that is just me. Good luck.
