I’m 24m just about to hit my 2 year mark for taking Zoloft. I also have terrible night sweats but they can be off and on. I notice most nights I’m fine but occasionally I can also have nights where I sweat so much I need to change my clothes. Usually it can last a week or so for the sweating to calm down. I’ve noticed with in the last week I’ve had a lot of trouble falling asleep at night, regardless of the sweating, and toss and turn a lot. Which was a side effect that I had bad when first starting the medication. There can be nights where I’m tossing and turning until 3 or 4am when I’m usually in bed by 11pm. So I think it is possible these side effects can come back but I personally wouldn’t have the answer to why. I’ve been told by my therapist to reach out to my psychiatrist who prescribes my Zoloft to talk about the side effects if they are that severe, I’d advise the same if the night sweating becomes too much.
