I took 2 10 mg doses of lexapro an had to stop due to horrible effects. I have not taken it in 8 days. I have never taken an antidepressants before and never experienced any symptoms before taking medication: panic attacks, extreme anxiety, horrible thoughts, extreme restlessness, muscle twitching. Although symptoms are not as bad when on the med, some still persist such as anxiety, restlessness, depression. How long will this persist. I'm at my wits end.
