It's been a long time since I have even attempted it so I can't remember any gassiness or constipation. I bought a bread machine because I was going to become a great gluten-free bread maker … right. I made some that was horrible and some that was not all that bad. But they all caused bloating and this horrible feeling of not being able to swallow it. I always felt like it was sticking all the way down. That's been my experience with the home made and the store bought.
