Feeling "normal" is relative, to how long you have your ostomy, and how you are managing it. Some never feel the same again, and it's understandable. Your body has changed, your routines are different, so it's unrealistic, to feel the same...... Aiming for a New Normal, is a challenge, but it will happen when you get proficient, and comfortable with successfully managing you colostomy.
I your goal is to "time" your output, then consider doing irrigations. If y ou don't know how to do it, request an ostomy nurse, and if that's not available, check out the videos on line. One is quite good, but the setting is in the hospital , so it looks more like a medical procedure. Basically, using special tubing, you are giving yourself an enema.......Once you fill yourself with water, you keep it in you for about 1/2 an hour... a special larger pouch, called a sleeve, can be attached to your wafer. When your body is ready, it will push the water/ feces out. I think the whole procedure takes about an hour. People do it either once a day, or every other day, whatever works for you. To the best of my knowledge, that's the only way to "time" colostomy output. I have an ileostomy, so my output goes continuously, and I wear a pouch with a spout on the bottom. I empty every few hours, depending on the output.. If you have any questions, ask colostomates who irrigate to write to you, to tell you what they do. Best of luck to you.
