Hi Ketchup. The drop in symptoms was artificially produced, and has draw-backs. Insomnia is terrible.
But it took away the bad taste in mouth, prostate problem, dry eyes, dry mouth [dehydration issues] itchiness, reduced sensitivity to light, and general allergies.
Keep in mind, this is only a temporary thing, induced by blocking some effects from over stimulation of mast cells.
It is an experiment to investigate mediator\receptor types involved.
The symptoms may return as drug effects wear down.
The real point of the experiment, was to see how much of the overall symptoms are related to innate immune function.
