My initial symptoms improvement (before switching to thiamin HCL) is credited to 500mg/day of benfotiamine. I must now reconsider choices. HCL is reported to be effective in one to two months from starting. I will continue with thiamin HCL for the remaining 5 weeks and after two months total if I do not see greater improvement w/ HCL, I will return to Benfotiamine.
