In the beginning, it worked OK for my anxiety. Not as good as Lexapro but I found Celexa to be a gentle start up and less overall side effects in general. But for the last four months I feel like I’m back to square one with my anxiety, and I even feel depressed. I’m currently on 20 of Celexa and don’t really want to increase it as I’ve read that it has some serious side effects at higher doses. My doctor would like me to add Wellbutrin, but I’m afraid that won’t be good for my anxiety. Has anyone else has Celexa stop working?
