I have been taking 10mg Lexapro since 2007 and I weaned myself off slowly with no bad side effects. After 3 weeks of being off the Lexapro, I got mad at something very little and it sent me into anxiety and panic attacks. I started back on my Lexapro after literally a week of non-stop attacks that I thought would go away. I have been back on the Lexapro 5 days and now I have insomnia and haven't eaten (little to nothing) in two weeks. Is this normal? Does anyone else have experience of going off Lexapro and needed to get back on it soon after?
