Hi, it does sound like you have developed a reaction to dairy but it is not necessairly the lactic acid. My Gastro Dr. explained that sometimes our stomach as missing other things that digest dairy not just the lactic acid. I was taken off all dairy and you would be surprised how much that really is when you think of cream soups, cheese sauces, etc. but it has made a huge difference in the bloating, gas and in my case nausea. I also took IBD Digestive Advantage and carry the lactic acid pills because sometimes it is almost impossible to avoid so it helps some. I also passed this on to a couple friends and they have been helped immensely by eliminating dairy. For cold cereal which I like I use either Almond Breeze, rice milk or soy mild but I like the Almond milk the best. Also you can keep it on the shelf till it is
opened so I always have some on hand. It can be used in cooking but it is more like skim milk. Try a week without ANY dairy and see how you feel. it is an easy, painless test.
