Greek yogurt, no sugar applesauce, white bread, pasta, rice, cottage cheese, scrambled eggs, mashed potatoes, grilled cheese, turkey and chicken, potato chips, pretzels, crackers, tuna, any kind of non-spicy soup without fiber, creamy peanut butter.
I did very low residue like that for probably a week and then slowly introduced more low-ish fiber foods like well cooked veggies, fruits without skin/seeds, red meat, etc.
I'm a year out and still slowly introducing higher fiber foods. It took about a year but corn/popcorn are now OK to eat for me
No meds except for Tylenol for pain management for the first week or so.
