I think the main concern for everybody with PD is to know the truth about relationship between long-term use of Levodopa and Dyskinesias and how Thiamine protocol can help.
Dr Costantini has told me that people who are taking Sinemet with Thiamine WILL NOT develop Dyskinesia even in long-term use.
I very much appreciate Dr Marco Colangeli for his professional opinion and other forum members for their inputs.
