So the past few weeks, I have not felt myself at all, stomach is swollen, feel sick all the time, no energy and sweating really bad in the night. The only thing I can think of is I changed my Sertraline brand (well the pharmacy did) and it feels like I haven’t been right since. I have been on Sertraline for a few years now and never experienced this but never had this brand? Unless it’s some sort of bug?
