Glad to see this topic pop up. Not glad you're having problems though.
I switched to sertraline from escitalopram in July (for anxiety). The nausea was awful for the first 2 weeks and got a bit better after that. But I'm so jittery and I tremble a lot. Apparently it's a common side effect. I also started having terrible night sweats which I assumed were hormone-related, but apparently it's common with sertraline as well.
I'm on 150mg though, so I'm probably feeling the worst of it. Going to try to reduce the dose in a few months. But it's hard to tell if the "wired" feeling is sertraline, anxiety or even HRT.
Trials of perimenopause I guess
