@formergardener my gastric problems started after I finished 23 months of MAC treatment- terrible abdominal pain all day long. I had all test that excluded many illnesses and the pain was still there. It was diagnosed eventually as bacterial dysbiosis( even though I took probiotic etc and had no gastric issues during the treatment). I contacted Michelle McDonald and she helped me step by step, week by week to get my insides work. Honestly it took 6-7 months. She worked with me on my diet and certain enzymes combination, gas relief meds which come without additives etc. May be you could try 2-3 conferences with her.
