~ Everything is fine. 3 days is not a concern Anything after 5 days would be a little different. Some will start with steamed vegetables then have protein and fat several hours later.Last night I had my old standby toasted cheese and tomato sandwich.
The night before was lentil soup.
Yikes! That sounds like a lot of food after being on a 72 hour fast. How did your digestive system react. Ok, I hope.
