Not sure you read the entire thread, but he was having some resolution from a certain vitamin D supplement.
Maybe pills arent the complete solution, but he already knows at least 1 did help.
This.
I now know that different sources of Vit D have vastly different effects on me. One of these did what I needed it to do, the rest have been varying degrees of failure.
How to isolate or replicate the effects, I do not know. It makes me question what exactly is the point of living when I know that I’ll never experience life the way it was meant to be.
