It is not very anti-depressant for me, but sure anxiolytic!
Try 30 (around an ounce) of good quality raw or slightly fermented cacao beans/nibs. They contain an endogenous cannaboid (anademide) and Theobromin sure is mood altering itself!
It may sound silly, but i've eaten at least 3 pounds now and it is the real deal for me.
It's nothing like chocolate.
Make sure to really eat at least 30g.
If nothing happens, try for at least 3-4 days in a row.
If still nothing happens, switch to another brand of beans.
