For several weeks her tachy worsened so much
This is usually due to increased potassium need. B2 is said to dampen the potassium thirst.
In my experience, I could never repeat the initial wakefulness I got from Benfotiamine. But then I found out it was due to improved folate utilization, and could not be repeated due to low folate levels. Folate also increases potassium needs, and B2 should also help with that.
As Dr. Lonsdale recommends, be sure to support B1 supplementation with a Bcomplex and minerals , esp. potassium and magnesium. I need to supplement other minerals as well, but I seem to be getting enough manganese from teas, spices and foods.
Sorry I don't have a protocol compilation.
You can get any vitamin delivered form from Amazon, iHerb, Vitacost, Swanson Vitamins etc. However due to customs fees I prefer to get my vitamins compounded locally, and unfortunately local pharmacies don't have all the hyped forms. So every now and then I do the online purchase.
