To restart lexapro at such a high dose--no wonder you have side effects. lexapro should be started at 10mg then increase after 1 to 2 weeks. Call you dr. and ask about this as I am not a dr. but take lexapro. Lexapro is great for anxiety, once it works, but is you are havng that much anxiety call your dr. and be upfront about the amount of axiety and ask the doc about an antianxiety medication, like klonopin or ativan for the rough times. are you seeing a PCP or a psychiatrist and do you have a diagnosis, all this matters, the psychiatrist is best at prescribing the correct corabination of medication. also at giving you a diagnoses that may be something different. I was diagnose with a totally different diagnosis that depression and ll my med were changed to the correct type and mg and frequency, I did and it made a world of difference.
Talk to your dr though. you do not have to put up wih the side effects.
Good luck and take care
