I had something similar happen to me in the first couple weeks post-op with Cream of Wheat too. I didn't actually have to run to the bathroom but I was really close to it. It did not sit well with me at all and felt like it just sat in my little sleeve like a rock (I made mine with Splenda brown sugar and water). I have had it more recently and was fine, but I have to wonder if sometimes our little sleevies just don't like certain foods at the start.
