Escitalopram
"The first six weeks were hell.  Increased anxiety so severe I lost seventeen pounds. I'm now five months in and have never felt better.  I'm on 20 mg  of lexapro once daily 20mg of Buspirone twice daily.  .5 mg of Clonazepam to be taken once daily if needed, I rarely need it.  I would suggest trying a physician that will prescribe a low dosage of Clonazepam from the start, it would have saved me a great deal of suffering .  Clonazepam is addictive so most doctors hesitate to prescribe it straight out of the box.  Good luck and stick with it."
