I also had bad nightsweats while on zoloft but I was also starting to go through menopause about the same time so I think it was mainly a hormone issue. I did start taking lecithin and it helped with the night sweats and eliminated the hot flashes also.
I've been on the 100mg for 3 months now, so I wonder if there is any hope of them getting better or fewer and farther between...
Yes, I had them on Lexapro, but they did go away fairly quickly. Once in awhile I still get them, but very rarely.
