The wife and I got it last month, I was pretty pro active from the onset and started a Vitamin treatment the next day of first signs of being sick. This list is what I used in addition to a B1 thiamine.
I use soluble C And D3 and did 10000 ui a day of each.
What is important to have and keep around is the nebulizer and Hyro peroxide. On first signs of the tickle in the throat start a hourly treatment. It will greatly reduce the chance of it settled deeper into your lungs ,also try and sleep sitting up as much as possible.
I had it beat in about 5-6 days but still stayed in bed for a 3 more day to just rest.
My wife was good as well but did not rest and pushed herself and it came back hard on her..
To the point I had to take her in to get checked. They sent her home with meds and it took a few days to get her better.. Scared the the chit out of me though to see her not getting better.
I will add to the list.
If you can get a Albuterol rescue inhaler to have around.
A PULSE OXIMETER to monitor your o2 levels.
DRINK A LOT OF WATER! FLUIDS.
In this day and age this is stuff to have on hand, ordering after the fact will prolong any treatment during the most important time.
Think of it like a bug out bag, it will be there when you need it.
