I was on 20mg of Lexapro for 10 years. I weaned from 20mg, to 10mg to 5mg to zero over a period of 2 months back in late September through mid November. My last 5mg dose was on 11/17/12. Overall I am starting to feel better everyday, but when I get stressed have been getting some heart palpitations. I was checked out and heart is fine. The other, nearly unmanagable issue is uncontrollable bouts of crying. I cry for every little thing. I broke down in front of my boss today! Not crying from any one specific emotion-could be happy, sad, stressed, frustrated...any emotion will trigger it and once it does the tears just flow. I cannot hold them back and once they start cannot readily stop them. Has anyone else experienced this and if so how long did it last? I have come so far and I hate to go back on Lexapro if I know this is temporary. My fear is that being on such a high dose for such a long time, that my brain can no longer function without it. How do I know if this is withdrawal or if my brain chemistry has been permanently altered from this drug? Thank you!
