Far too many anti -depressants are handed out by doctors who either can't be bothered to listen to their patients needs or who are too busy and have far too big a caseload to spend the time with patients.
Also too many people just take a few days worth and when they see no immediate results shoot off back to the gp demanding something different, you wouldn't expect immediate weight loss after 2 days on SlimFast !
Hope your new meds are fine for you though, I got prescribed Xyzal for my hayfever that had the " may cause drowsiness" warning, I was falling asleep by noon every day !
