You’re welcome! Your persistence with experiments and research will lead you to more answers for yourself and better health. They have for me. I never gave up. In fact, I know more now about my health issues. I believe high B12 blood levels can be associated with liver disease. I am sure you will figure out the culprit with your situation. I have tried aceityl-l-carnatine but it offered no help. The curcumin is a supplement I have been taking for years. Lately I have combined it with ginger for my nausea. I feel it helps but not significantly. I do get the typical annual blood draws for labs and so far no concerns. Results are within normal limits. As for the aceityl-n- cysteine I do not take a supplement. I eat plenty of foods daily that contain it. I feel eating a well balanced diet does not require heavy supplementation. I mainly take fish oil, probiotics, and curcumin….no medications at all. I rely on exercise and healthy eating. I feel the more I practice tasks, the more my brain learns the new pathways to perform those tasks. This is neuroplasticity. By using neuroplasticity tasks eventually become easier. As with anything else it also takes patience so hang in there. Sounds like you are determined to get answers. Don’t give up. Wish you well. Toni
