I've been in a situation like this three times (twice in my youth and once about a year ago). Five days without any food, only water and herbal tea. Only the first 18 hours or so are a problem (depending on your eating habits) day 3-5 are the best, because your mind is really clean and you don't feel any usual discomforts from eating late or eating something you shouldn't. You do feel light and weak of course and I'd recommed avoding any hard work but otherwise 3-5 days without food is completely fine (assuming you don't have any conditions that require a stable intake of food).
