But didn't you get palpitations when reduced copper? (or lowering it by zinc)
Caution about that much copper in the long run! I tryed to remedy very low zinc serum levels with increasing amounts of zinc. Above 50 mgs I followed the advise and balanced with some copper. Already 2mgs copper per day for about a year let my copper shoot levels shoot above normal. Which I haven't been able to correct fully after many more years.
At least also get serum copper tested, if taking such high doses of copper for loger times.
Copper deficiency could be driving much of the current burden of IHD in the population. Copper intakes have been declining and it appears that a large fraction of the population does not even consume the recommended daily allowance (RDA) for copper3 (0.9 mg per day) let alone an optimal intake of copper (2.6 mg per day).4 Thus, it appears that much of the population is at risk of inadequate but especially suboptimal intakes of copper.

I'm sorry to hear that benfotiamine didn't help. There is always the option of trying other forms of B1 e.g. sulbutiamine, allithiamine. Although they are generally considered equivalent, some members report different effects from different forms of B1.
Also, it is probably worth reiterating that magnesium is important as it works with B1 and helps the body retain and utilise potassium.
