These meds (antidepressants) have both pros and cons, and even off label uses.
Many I know have used them most of their lives, while others have not used them
at anytime in their lives...
In my life, I used an anti- depressant twice for hopeful relief of nerve pain after an
injury and for another condition. Both times was a year of use, then tapered off
the med both times.
The one med was Amitriptyline, yes weight gain.
The other med years back was Zoloft, now that helped a great deal at the time, but
after a year I chose to discontinue the med, again with careful tapering off, under
doctor supervision.
