I have found a daily fix to rid me of depression, I take vit c, B3 and a B6 complex, and GLA, GLA is magic, it can be found in evening primrose, to get the desired amount of GLA you may want to take 2-3 caps a day, or go for a GLA complex that has the desired amount, its like magic!
PS this comes from a book called 7 days to sobriety.
