...be VERY wary of any "authority" that claims their basic protocol cures all COVID. It is VERY irresponsible to do so and shows a real lack of true character, and certainly a real disregard for others' health.
What's the reason? Due to the nature of COVID, you need huge data sets to understand how anything is working.
Even if that "authority" carefully observed 1000 patients personally, and their method worked on all of them, the data would almost be meaningless.
Plus, things like Ivermectin ONLY work with early intervention, when the main threat is the spread of the virus through the bloodstream from the nasal passageways and the lungs. After that, it is close to useless (but not completely useless). Many people have died because they believed Ivermectin would cure them, because they were not taught that it MUST be used early in order to be completely effective.
I tend to move toward hypothyroidism, and it used to be a huge problem. I did vast searches, and came to the understanding that there would be no recovery WITHOUT iodine. This was a catch 22. I don't believe in permanent catch 22s, so I kept searching, ignoring all of the fear-mongering (but of course taking NOTE how hard iodine can be for some).
Then I found, IOSOL. That was the exact product I needed to get my body USED to iodine. I did that for seven to nine months, THEN switched to the "scary" Lugol's. Don't listen to the naysayers, they don't understand the problem with IODINE, and IOSOL's solution. Iosol can be used to acclimate the body to iodine, but not for iodine therapy itself as a healing modality.
I don't see why you wouldn't be able to use IOSOL with a salt pipe. It won't be as effective, but IOSOL is the only hope a person has who has tried other forms and failed (generally, not directly related to COVID).
Due to ethics, I can't make direct advice regarding COVID. But we have a LOT of research work posted in the "internal infections" sub-forum, and I suggest exploring them all looking for inspiration.
But of course, KNOW THYSELF FIRST! ...which you are pretty good at!
Yes, I don't think that you should nebulize a bunch of things at the same time.
Just so you know, my experience to date is that silver is "pretty good", but H2O2 is much more effective with COVID, probably because it stays active longer in the bloodstream, and it has a higher oxidation potential.
The best "drug" out there for this type of infection, currently, is high-quality olive leaf extract. However, you must note that it works by viral replication inhibition. If you hit ANY type of flu virus FAST, you'll never develop advancing symptoms. With COVID, if you keep the nasal passageways virus-free, you will not likely develop the disease, UNLESS it makes it through the stomach and attaches to ACE2 receptors in the digestive tract (clay is awesome for this expression).
If your lungs, lung capacity, and chests muscles/abs are still in good condition, you could slowly start to use breathing to modulate the immune system... this is one thing I haven't written about anywhere here, as it is very problematic for many.
You could also use DEEP meditation practices to put the body into a state of healing, but most meditation can't be done with acute illness, it must be sound-assisted or ultra depth hypnosis. Basically, you have to put yourself into a deep healing trance, with theta and delta dominant brainwave states.
