so I've been taking 5-htp for about a year at this point. I started taking it for good sleep. I noticed a couple weeks ago when I stopped taking it, that I got a little depressed so I started taking it again. What's the best way to come off 5-htp...is there any other serotonin boosters i could take briefly to help me stop taking 5-htp? I take 400mg a night.
