I am in full blown Graves Disease with a non functioning nodule , awaiting to have a thyroidectomy. For the Graves, I am taking propranolol, vitamin d3, vitamin c, horehound drops, reishi mushroom capsules and turkey tail capsules along with tums and otc lansoprazole for acid reflux that I have had for years. The past few days I have been taking anti diarrhea medicine ( not bismuth). I then added a kefir shake. Today after having a nice bowel, a few hours later I was back to having a very watery bright yellow bowel that had a couple of black flakes mixed in floating around the bowel and what appeared to be kernels( I have not eaten corn). The black flakes were roundish, flakes. Another worry.
