It was hard for me to tell too. I started Lexepro myself only two months ago. The first month I felt shakiness but it tapered off, but my dosage was upped from 10 mgs to 20 mgs and so now I am experiencing the shakiness again.
I would have to ask how many panic attacks you had prior to the Celexa and how anxious you were, and then ask you the same questions about
how you feel right now.
I know the Lexepro is working because I have only had two or three or four panic attacks in the past few weeks, whereas I was having them everyday before the Lexepro.
I also take Ativan, which is a benzo. It calms me down if I'm feeling anxious or panicky.
