I have head ache, sweats and cough. Dr would not let me come in. Would not prescribe me HCQ or Ivermectine or could loose her licence. Gave me a hotline to call for 100$, Hotline booked until next Monday!!!! This is how they are killing people. When you get worse they tell you to go to Emergency Room and get the final kill shot!! Remdesivir and a vent. If you argue for cures instead they sedate you.
I have been taking C, D3 and zink. also made some Lemon peel and Grapfruit potion. I guess we are on our own.

I've heard 500 mg of quercetin twice a day in addition to what you mentioned works well also.
