If you get COVID you can try speakwithanmd.com for a telemedicine appt., which I haven’t used but word on the street they are cooperative about HCQ + Az, however that may depend on the doc you are hooked up with.  Dr Stella Immanuel has been in the news recently and is a bit of a wackadoo apparently but she has implied she will write prophylactic HCQ prescriptions to people, which would prob. be 400mg per week.  https://speakwithanmd.com/intake/drsimmanuel/telemedicine_add_patient_wizard.php  Maybe there are other doctors willing to prescribe prophylaxis as well on there.  You could save it for a full blown infection (3200 to 5000mg over the course of a week would be a decent dosage for an actual covid infection.) so that you could start medicating as soon as you have symptoms ( Im not convinced that 400mg a week prophylaxis will be enough to totally prevent COVID but it might).  Save any antibiotics like tetracyclines, doxycycline, erythromycin, azithromycin, ciprofloxacin. These likely all inhibit the virus and can be used with HCQ.  Alternatively you can chug a lot of quinine tonic water.  Quinine is really similar to HCQ and there are about 60mg of quinine base in a liter of tonic. 5 liters a day would be a low dose but enough to make a difference if you started on day one. You could do as much as 10 or 12 liters a day and still be in a safe range (for most people). Schweppes seems to have the most quinine at around 68 mg per liter.
