We started with 1g of thiamine per day for my husband.
500 mg before breakfast and 500mg before lunch since 5 days.
We have not noticed any improvements yet but the only symptom we found to be on the little worst is his speech.
( increased slurred and stammering ).
He had speech issues prior taking to thiamine too but we find that they are getting a little worse now. Except that all of his other symptoms are same.
Also after he takes sinemet all his speech symptoms go away.
After the 5 days on thiamine we find that he has a little difficulty in speaking even when 'ON'.
Pls advise me on the dosage whether to increase, decrease or continue on the same for some more time.
