Hi, I can't help much but to add Benfotiamine has been a life saver for me. It really helps with the burn and I wont go a day without it.

Also, I take B12 daily even though my test was 4,000 (I did not stop taking supplement before testing) I would suggest you take B12 also, as your number is not high.

Also I would suggest magnesium. I take it and I also bath in epsom salt, which is magnesium, as it goes into the blood stream fast when I take a bath and really helps.

Good luck, Im sure others will come along with more advice.

Oh, and I think it is very normal to have ups and downs. I can go days doing great then have a few days where nothing I do helps. It's just part of the game.
