Welcome to the forum.
Refer to your doctor's or hospital's Post Nissen Diet. If they didn't give you one you can look up some very good ones online. I like the UPMC one. But you really should ask your doctor about this. Some of us were on soft foods for months, some only a day or two.
The critical thing about eating post Nissen is getting the food swallowed past the repaired valve (LES) because it's been wrapped with part of your stomach. Part of the solution is choosing foods that will go down; another part is chewing food well enough. At about 2 weeks it's often posted that the swelling is at it's worst. Even if you go home able to eat anything, that can change and scare you to distraction when the wrap swells up. After all, there was a lot of damage, cutting and sewing and tying that happened to your stomach, esophagus and diaphragm. It can be worse if you had a hernia repair.
Personally, I don't eat cereals except for a very few made from rice, which don't have enough fiber to do any good. I'm allergic to the sulfite in the molasses and on the dried fruit. I never found that cereals made much difference before I found my allergy anyway. It's so easy to get fiber by adding a little Benefiber (available in generic). But Miralax (also available in cheap generic) works best for me. They both dissolve in water or anything with water in it and are tasteless. I put them in coffee, tea, soup, applesauce ... It takes 2 - 3 days for them to work, so don't overdo! Once a day of the recommended dose works for most people.
If you're using pain meds still, that's probably the cause of the constipation. When you get off the meds the problem should go away with a little time. If the problem is really bad, consult your doctor. He should have given you a Rx for a liquid laxative, although there are a lot of pretty good tablet ones.
We're not doctors, so anything you read is just opinion and experience from lay people. Your doctor knows you best.
