@Graham What does "is X healthy" mean? Is it asking whether something is dangerous? Whether something has health benefits? Whether something should be done less or more? In your answer to that question, for example, you only addressed the "is it dangerous?" interpretation, even though the question also asks how many times it is good, which might be interested as asking whether it has health benefits. I think those questions are unclear without more detail added.

Just for the record, a question being closed for one reason doesn't mean every one of those close votes was for that reason. I am pretty sure I didn't pick POB. (possibly "unclear" - it was badly worded before the edit and an "is X healthy?" question)

I think it should be noted that those comments were not on the revision of the answer you posted, but for an earlier one where you called 5-HTP an SSRI and antidepressant and at least seemed to imply that SSRIs help with weight loss: "in general SSRIs are considered safe (in comparison with other antiobesity agents)". Without that knowledge, the comments you quoted about SSRIs and weight gain don't make sense.

@Swapnil I'm confused - where did anyone say anything about pain killers?

It would help if you could say what question you are talking about
