I noticed that you mention that you eat oatmeal in the morning. I ate oatmeal every-morning since starting this diet and noticed that I have lots of gas early in the day. Just last week I switched to having safe cereal and rice milk for breakfast and it did help with the gas. I love oatmeal and I still eat it, just not in the mornings.
I am really sorry you are having such a hard time. I also take Acacia in applesauce first thing in the morning and at bedtime. This past weekend I started taking over the counter Zantac (generic brands) and that also seems to help with the gas. Hope things get better for you because I know how this thing can make your daily life at the least a challenge at the worst pure hell. Good luck...
