My biggest complaint with this whole IBS diagnosis has always been pain (always on the right side) and a tendency towards constipation. Recently I started taking calcium supplements with magnesium because I am also experimenting with my diet and have cut out dairy products. Now I've noticed that my "C" now switches back and forth with "D" symptoms. The pain is still there and I can't seem to track what triggers it. My next experiment will be with wheat products. Have any of you experienced this? Can it be the magnesium? I don't know what to think at this point!
