I tried Lexapro for a few weeks and I did have increased sweating, especially at night. Same thing happened with Zoloft (but not as bad) and now with Wellbutrin, and it's getting worse. I'm sure it's partly menopause, but it definitely intensifies with meds. Lexapro also gave me intestinal problems to the point I was weak all the time. I have chronic heart burn too, but I don't think it has anything to do with my meds- it's acid reflux, which tends to be worse at night. A Prilosec a day keeps it away.
