Now that you mention it, Ginkgo Biloba has antidepressant qualities. Quoting Wikipedia...

"These extracts are shown to exhibit reversible, nonselective monoamine oxidase inhibition, as well as inhibition of reuptake at the serotonin, dopamine, and norepinephrine transporters, with all but the norepinephrine reuptake inhibition fading in chronic exposure. Ginkgo extract has in addition been found to act as a selective 5-HT1A receptor agonist in vivo."

After your done experimenting and reporting on SAM-e, could you try and reported on Pregnenolone, Ginkgo Biloba, or N-Acetyl-Cysteine? Thanks for documenting your experience on SAM-e.
