I have been feeling very upbeat about thiamin, especially after hearing from Dr. C. Then I talked to my doctor (yes, a movement disorders specialist) and took a nosedive. I asked her if she was familiar with Dr. Costantini, and she said no. I summarized his work with thiamin. She scoffed, "He just made that up." It was so dismissive. It sunk my morale since she has such high creds. Friends in my support group and exercise groups say I'm very lucky to have her as my neurologist. Now I don't know who to believe!
