I stopped eating cereal with milk before rides, and then I cut it out altogether. Starting having dry whole wheat toast, black coffee and grapefruit, maybe an egg, in the a.m. Much better.

But at first I cut out most processed wheat products (my husband was still making baked bread, so I figured since it was homemade I could toast it and eat that, and it didn't seem to affect me.) Cut out all pasta. All white flour products. All desserts for a month. All scones, muffins, danishes, whatever. I cut out all dairy for a month. Didn't even eat yogurt. I basically ate only fruits, veggies, meat, some beans (but not like I ate beans before) and the homemade bread, toasted. Bazinga.

Since clearing up I slowly reintroduced a couple of things like hard cheese and have stayed clear. I did have a bowl of cheerios with milk and immediately felt stomach cramping, congestion, and tiredness. So, I think it's a combination of cow's milk and processed wheat foods.
