I have been taking Lexapro 10mg for 3 weeks now just woke up a few days ago feeling sick to my stomach and have been feeling that way ever since. I am going through menopause so not sure if that's part of the reason for sick because of hormones or medicine. Doctor says it hasnt been long enough on meds to be the cause and nausea isn't a side effect with the Lexapro. Can someone tell me have they felt like this on this medicine?
