Sounds more like a dairy allergy to me. I've quit both. As a former snorer, Farty McGee, and bloat king, I will testify that BOTH grains and dairy can easily be lived without. Dairy also makes me crave food. I think it does things to my system that tell me to EAT EAT EAT. So I have a cheese stick once in awhile if I'm jonesing, or buy a tiny brick of raw, organic hippie cheese and eat a tiny amount daily until it's gone. But I regularly go weeks without any dairy, and those are the weeks I can see my abs and have smoother energy between meals.
Acid reflux, bloating, gaz, constipation, cramps, really bad menstrual cramps, headaches (tension), my sinuses feel blocked almost all the time, palpitations, cravings like I am afraid to lack of food and cannot concentrate, no energy, anxiety with sometimes panic attacks (though it's rare).
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
