I loved my Paxil, it saved my life!!! It cured me of my anxiety attacks and minimized my general anxiety and thus my depression also went away.

Neuro/Psych started me out on 20mg and through the 7 years I was on it, moved up to 60mg, then it stopped working..
PC Doc changed me to 40 mg of Prozac and I've been on that for 4 yrs and doing great.
Years ago Prozac made me jittery, but after Paxil stopped. my Doc said it may work again, so I tried it and now, I love my Prozac.
I imagine Celexa is a little like Prozac and probably is not working for your Anxiety, right now?
Good luck!
