Happened to me with it, happens to many who take it. During the time I was on
Lexapro I started taking 3 showers a day,
and often had to get up
and shower so I could go back to sleep. However, the prohibition of 5-HTP does apply when you take an SSRI -- you shouldn't take both. 5-HTP can also cause night sweats in some people, though probably fewer than Lexapro. I am wondering why you would take it after your doc correctly told you not to, but that's another issue.
