Is this nuts?

So just need to vent. I was in the ER last week and newly diagnosed with diverticulitis. The ER doc told me to eat a bland diet that day and the next day resume my normal diet. When I got home and did research I realized that was nuts. By that time a day had gone by but I stayed on a bland diet. I’m following up with my primary this week who was on vacation last week. But does anyone else think that is nuts? I think I should have been on liquid diet. And the idea to resume normal diet within 24 hours??? Anyone else ever hear that?
