Just wait a few days and try again. We all progress at varying speeds

First 2 weeks I was told to stay on liquids only. I found that I tolerated broth and creamed soups made with skim milk the best. I could only eat/drink 2 mouthfuls at a time. Had to wait until I could tolerate it again. At 2 weeks I started real food and really had no issued other than the 2 bites and I was full. I still can't eat a whole lot and I am 8 weeks out. I do have to eat frequently to get my protein in. It will get better and easier with time. I can definitely drink more now. I still have to drink protein shakes to supplement my protein intake. If I don't get enough protein my weight loss stalls.

I was supposed to start soft food at two weeks but waited one more week because my stomach was not ready.

I did have the same problem but once I learned to take it even slower I was ok. If I were you I would stay away for eating foods that are completely dairy based. Either slowly incorporate dairy in or stay away for now. They can be pretty harsh on the system at first.
Are you drinking vegetable or chicken broth? If so, you should try transitioning to soft foods with that as your base. Bring a small pot of stock to boil. Add some vegetables like carrots or potatoes. Cook all the way through and then blend it up. This will make it a little thicker of a soup. Then add a bit of dairy if you wish to make it creamier. As you feel better start leaving in chunks of cooked vegetables or adding in beans.

Thanks janellak, I will try these things out.
