I agree with the other comments. If you live in a large city you should be able to get the items delivered by Gojek/Grab same-day from a apotek or Tokopedia.Any suggestions or comments?
- Vitamin C, D and Zinc. 5000mg/day of C and 20,000 IU/day of D, Zinc 100mg/day. It is impossible to overdose on C and vitamin D would take months at 20k IU/day begin to have problems, and you will know within a week if symptoms are getting better or worse. Also be aware Zinc causes nausea and vomiting in a significant percentage of people, do not be alarmed.
- Get a 'pulse oximeter'. They are only about 200rb and are the best way to know if a Covid infection is worse than your symptoms are indicating. Doctors worldwide have reported patients with only moderate symptoms coming in with oxygen levels far below expectations. A healthy person will be 95-99% O2 level, anything under 90 is concerning, and below 85% I would go to the hospital.
A hospital will be able to provide oxygen and most or all of the MATH+ protocol that has become the international standard. Indonesia is also participating in some trials of common, low risk, and potentially effective drugs like Ivermectin, Hydroxychloroquine, and Calcifediol (hospital-grade vitamin D). Make sure your doctors are aware of any heart health history before giving Hydroxychloroquine.
That is what I would do. I am not a doctor. I am not your doctor.
