I would, at a minimum, add in a good B complex. If you have never taken a B complex, the niacin can cause a niacin flush so we take the B complex with a full meal to slow down the absorption. There are B complexes that have the no flush niacin if the flush is too uncomfortable . I would look for a B complex that has 100 MG of B1. I think the benfotiamine form is more effective. Or just buy a separate B1 at this time and see if it helps.
