Regarding a substitute for HCQ:
Schwepps Tonic Water contains appx 80 mg Quinine per liter.
Thus as per the Zelenko protocol, 3 liters of Schwepps will fulfill a single dose of the Zelenko HCQ prescription. While it seems a lot of tonic, it is easier for the sick to drink Tonic water than plain, as it has taste.
Note: A marker for the Covid-19 is loss of smell and taste.
Loss of smell and taste is also a symptom of Zinc deficiency.
A friend was sick with Covid last month. Did not know about HCQ. Agreed to drink 3 liters/day of Tonic Water. Dropped it off daily, along with a bottle of Zinc Glyconate lozenges from Life Extension Foundation directed to take 220mg/day of same. Began to feel better 16 hrs later, and sense of smell and taste returned 48 hrs later. Back at work now.
3 liters? heck of a lot of sodium in one day, may not be good for some people.
