I am using the Gupta program to recover from long-covid. After multiple years and going to many different doctors, this is the only thing that has actually helped me. I have seen noticeable improvement in my issues with taste and smell. I can actually smell things more often now, which is great! And foods that tasted awful like onions are tasting normal again. I have good days where I actually have some energy more often, but my energy level is still nowhere near normal. I have a long way to go, but I do believe in this program since I am already seeing some results.
