Anyone who tells you anti-depressants are not habit forming is a rep for a pharma co. that has not been sued to change their stance on that statement yet.
There are problems with anti depressants being over prescribed and misprescribed to people who should have had a talking therapy, and they are difficult for some people to stop, but calling them hanit forming is incorrect.
Apparently there may be tolerance for antidepressants: https://en.wikipedia.org/wiki/Antidepressant_treatment_tachy...
>ADT tachyphylaxis incorporates drug sensitivity as a potential causal factor for the decreased response. However, tolerance provides a more accurate explanation. While the exact cause of ADT tachyphylaxis in individual cases is unknown, drug tolerance is a more comprehensive model, as it includes mechanisms of pharmacodynamic tolerance, metabolic tolerance, and others.[7]
