I noticed the acidic stomach in the beginning. I attribute this to the toxins related to the die off of pathogens. It does go away. With me it comes back occasionally. I suspect this happens in the intestines as well. It does help to take an extra supplement of probiotics once in a while. It also helps me when I take a little baking soda. It has already been said how helpful it is to ingest more alkalizing foods and drink more water.
