My husband started with 1g of B1/ day and noticed some improvements especially during hus off times within 2-3 days.
After 10-12 days his dyskinesia suddenly increased to the point that he couldn't sit still when on medications. So we immediately stopped B1 and after 5 days he got to normal again. At this time we didnt realise it was because of B1.
So after a week we started with 500mg, continued for another week and then increased to 600mg but there were no marked improvements and he missed the improvements he experienced when he was on 1g ( he was able to workout in his off times treadmill, cardio,cycling) and so we again jumped to 1g and immediately started noticing the improvements within a day or two. All was good for 10 days but again his dyskinesia increased and we had to stop it immediately and the dyskinesia subsided after 4-5 days.
So now it was clear that it was due to B1.
Are these signs of overdosing? Is 1g too much for him? He has improved off times at 1g but increased dyskinesia. However B1 is supposed to reduce dyskinesia and not increase if this is the ideal dose for him. Besides increased dyskinesia he doesn't have anyother signs of overdosing.
Any advise would be greatly appreciated.
