I am experimenting with THC, CBD, and Lecithin, so far.

I started taking Lecithin about a week ago. On Saturday I took 40mg CBD. On Sunday (taking Lecithin as usual, but no CBD) I felt absolutely fantastic. In general, I have felt better for the last week. I'm also going to the gym about 4 times per week.

Completely not conclusive yet but I am continuing to investigate.

EDIT: Forgot Magnesium, for me this seems useful for anxiety.
