Have to say as a general rule that it will take about 6 weeks for an anti depressant to reach a therapeutic level in your body depending on the dose that your doctor has you on. If the doctor has increased the medication then that may account for the change in how your body is responding.

I took Lexapro about 8 years ago and I remember high anxiety levels and abnormal sweating. If your body hasn't settled by now in taking a certain medication then there are chances that it isn't the best one for you. Please talk to your doctor about this.

Hope you can find something that suits you better.
