I have had total exhaustion, brain fog since I had my left kidney removed 12 years ago. I have chronic pain in cervical, thoracic, and low back due to MVA 15 years ago. Pain mgt doc thinks it triggered fibromyalgia, but have been exhausted long before this. I also have chronic migraines and sinus infections & have been tested for just about everything my GP could think of and nothing comes up wrong and have been sent to lots of specialists to no avail. I have read about acetyl-l-carnitine and deanol (DMAE) for these conditions I ve read conflicting dosage info, and would like to know dosages recommended to start with, and other supplements that are used for these symptoms. I have also read about brain and energy boosting supplements, but would rather start with one supplement at a time to see which is beneficial.
