So...I suppose the treatment for the giardia was Flagyl (metronidazole)... it usually is.
Flagyl is a known nerve toxin.
Have you tried Benfotiamine? This is a form of thiamine and may help since Flagyl involves interfering with B1 metabolism. I am not sure about the time delay factor, but I'd try it anyway.
