This is a very interesting line of thought. I just ate a bowl of oatmeal with about 2 ounces of soy milk and a peach cut up in it. I took 2 650 mg. HCL (usually I would just take 1) and I don't feel the warmth yet eiter. I was sure I would. So, I may keep up with the 2 650's for my meals today, and then try upping to 3 tomorrow, and so on.
I also like Dr. Murray's stuff. His Iberogast is aces for tummy woes.
