That could definitely happen. When I was on Citalopram I felt fine, but one day my uncle told me he was concerned about me because I was sitting on the couch looking like a zombie. But I was also on several other meds, but I felt fine but my uncle could definitely tell I wasn't my usual self. Worst part of Citalopram was coming off of it. My doctor told me to just stop it the same way since I didn't feel depressed at all. A few days later I was watching TV having a good time and out of nowhere I started crying for no reason at all. My doctor said I started to cry because I was still depressed, but no, I was at home watching TV and enjoying prime time TV when suddenly I started crying but at the same time I didn't feel sad at all. I felt confused because that had never happened to me before and hasn't happened since I was on Citalopram. My doctor msfe me wean from it for a while, but even while weaning off of Citalopram I still found myself crying when I wasn't sad or had intense emotions of any kind. One time I started crying while my mom and I were driving on the freeway. We. Both looked at each other confused. But I only stopped Citalopram for good when I couldn't get my refill despite me trying and paying out of pocket money to get a refill because it sorta felt like the carrying was just some sort of allergy reaction in that my eyes waterd way too much for it too be allergies. When I finally saw my doctor who told me to just avoid it and it if was out of my system then he wouldn't give it back to me unless I explained why I thought I still wanted it. I told him I hate citilopram so he said to not take it any more because it was already out of my system and that was it. But my friend who was taking it for IBS stomach issues got ED from citilopram while luckily didn't have that problem.
