Supplements with evidence of boosting serotonin are worth a try. It costs about $65 at Whole Foods for 2 months supply of Tryptophan, 5-HTP, L-theanine, St John's Wart. Also consider saffron extract and fish oil or falxseed for Omega-3s.
I will look into these, thanks! I have found that I feel my best when I'm taking some vitamin supplements. Very likely a placebo effect but hey, if it works it works... Also I am taking some melatonin to hopefully help with the insomnia I tend to get when going off cannabis.
