I have only been on 20mgs a day of lexapro for 2 days and wasn't able to deal with vomiting every 20mins, pain all over body , cold sweats, inense heat , jaw pain, no sleep, constipation, skin crawling, etc.. I had to stop it was too overwhelming. Can someone tell me how long before its out of my system and what can I take to help with severity in vomiting. Pls help.
