a few months ago i was tapering off of anti depressants. i was still taking a little and the 5-HTP i took made me have full body tremors, while puking for 3 hours straight. i overdosed on serotonin.
def check with doctor first. i also heard of people starting a supplement by taking a small amount at first, to see how it affects them.
i think vitamins are the better bet. i take vitamins b2, b6, omega 3, d, and magnesium. i will not touch a supplement again.
