Did you have a hard time waking your digestive tract from its hibernation afterwards?

I did a 5 day fast once and it took me a week more before I could poop again. These days if I fast longer than a day, I eat one large raw carrot each morning, it’s caloric value when raw is basically nothing because the body has to spend so much energy breaking it down, but the fibre in it keeps my digestive tract ticking over just enough so it doesn’t hibernate.
