Sertraline for hot flushes

Hi has anyone been put on sertraline for hot flushes. I’ve been on it about a month and I’m not sleeping at all like an hour or two a night. It’s been awful. I’m also on zoladex and anastrozole. 

my anxiety has gotten better though but still having hot flushes and night sweats although not as bad. The lack of sleep, dry mouth, upset tummy and headaches don’t seem to be worth it and I don’t know what to do.
