Same thing with me. 10,000 units of Vitamion D for years, zinc, C, the whole shebang, and I got Covid two years ago, horribly sick, and I’ve been horribly sick with bronchitis for five weeks.
So sick that I lost 20 pounds in three weeks and spent most of those weeks in bed, too sick to move.
It’s not a miracle drug.

Hope you do better in the new Year!!!
