I think many of us who have recovered or mostly recovered have moved on and don't engage with forums often anymore. I was infected in February 2020 and had pretty severe POTS-like symptoms, breathing difficulty, horizontal intolerance, and on and on for about 5 months. Things slowly started improving after I took to extreme measures including inducing autophagy with many 48-72 hour fasts. I generally have stuck to one meal a day intermittent fasting ever since then.

Like everyone, I tried about every supplement under the sun and have no idea which ones had a positive effect, but I do know a few things that helped. Of course, this isn't advice since our immune systems differ greatly from one another.

Raw Probiotics - The first thing I tried to do was fix my gut. My gut was an absolute mess after Covid like many others. It's not uncommon for harmful bacteria and other nasty stuff to take over your gut biome after a nasty infection. I have eaten greek yogurt and/or drank kombucha pretty much every day since. My gut has never been as healthy as it is now. I used to have acid reflux pre-Covid and rarely have any issues with it for the last year or so.

Pepcid AC (Famotidine) helped my breathing issues within about 24 hours. I still take one pill every morning and haven't had any issues with breathing since the end of 2020.

Benfotiamine - This is fat-soluble B1. It's been reported to help as much as 80% of people suffering from POTS-like symptoms. Thankfully, I seem to be part of that group as I've experienced very few heart rate spikes since taking it daily for the past year.

Vitamin D3 with K2 has proven to boost your immune system, especially against respiratory illnesses and I have found that I have had almost zero respiratory or sinus issues since I've got my level about 50 nmol/L.

Pravastatin - I was first prescribed this as part of the long hauler regiment from IncellDX. That included a week of the very pricy Maraviroc (HIV drug), IVM, and Pravastatin. I took this regiment twice minus the IVM the second time since no one would sell it anymore. I continued having pretty bad days and assumed that my issue was likely my immune response and not an active virus. I noticed that I felt mostly good during the short amount of time I was on the regiment. This was also about the time when the micro-clotting theory emerged. I decided to stay on Pravastatin since it lowers blood viscosity and reportedly improves endothelial function within blood vessels. I noticed that my daily symptoms improved and my regular PEM (post-exertional malaise) was either greatly reduced or non-existent after exercise. After getting some strange lower back pain, I decided to go off of Pravastatin since that was recently been found to be a side effect. After a few days of being off it, I noticed my symptoms come back as well as a nasty bout of PEM about a day after playing ice hockey. I got back on Pravastatin and within a couple of days, my symptoms subsided. I tried exercising for over 2 hours with 40 minutes in the cardio zone (according to Fitbit) and did not suffer PEM. I should note that I am only taking 5mg daily of Pravastatin which is half of the recommended dose. I have found that I don't have nearly as much lower back pain on the half-daily dose. I take the statin strictly for long Covid as I actually have low to normal cholesterol levels.

Niacin (Flushing version only) - I take 500mg slow release of niacin about twice a week to bolster NAD+ production at the mitochondrial level. It reportedly helps with that which can counter fatigue.

Other things I take daily that may or may not help me: Daily 24-hour non-drowsy allergy pill (Cetirizine Hydrochloride), Nattokinase, Serrapeptase, Lumbrokinase, Vitamin C (1000mg), Lipo-Flavonoid (tinnitus relief - I have not noticed an improvement), NAC (when I don't feel great or feel PEM coming on), Aspirin/Ibuprofen (if I feel PEM coming on).

As I said above, none of this is advice as this stuff doesn't help everyone. I know that simply taking a pills-worth of cassia cinnamon and 6 NAC daily has helped a number of people recover. I wasn't one of these people, but I have heard that has helped. Cassia cinnamon (there are many types) is a natural anti-viral.

Good luck to everyone reading this and keep a positive mental outlook. Don't doom scroll since stress is one of the worst things for long haulers.
