Due to constant stomach pain I'm going to try going back to a full liquids/soft diet for a bit. I think part of the issue is having difficulty digesting dairy. I need suggestions for getting 15 grams of dairy-free, soft Protein 5 times a day. I'm also curious if others have experienced bloating, gas and feeling like a brick was in their intestines even with daily bowel movements?

It definitely sounds like it could be lactose intolerance. In the very beginning I had this issue and had to switch to lactose free dairy products and had to change to a new Protein drink as well.

Now my case was fairly mild but it was miserable and I was not getting my protein in.

I switched to lactaid brand cottage cheese because I did very well with it. Also I started using Premier Protein ready made shakes and still use them 11 months later.

You might try also re fried Beans. Puréed chicken, scrambled eggs.

Try adding unflavored protein powder to your foods to get the extra protein that you need. Try non dairy foods like almond milk, almond yougurt, etc.

Prior to surgery I could not have milk, cottage cheese or ice cream even if it was lactose free, however cheese was not an issue. I do not think it is the lactose that causes the problems, possibly another component of dairy. I'm hoping to find a completely dairy free alternative to Protein without whey or casein. I wish there was a low carb, high protein almond or coconut alternative but I have not found any that are adequate protein sources.

I do not love them, but Isopure may be an option. Not sure if you may be allergic to whey?

If so, get a non-whey Protein...

Best of luck to you!
