Go on the Facebook B1 Therapy site. You must buy Daphne's book which is not expensive and very, very helpful. The professional, Sergio Pieche, also advises. It is not quite as straight forward as it sounds. Some people don't need as much B1 as others and magnesium and b complex should be taken. I know Dr Constani condoned taking ldopa with B1 but you read other peoples experiences and it is very helpful.
