anxiety and stress
"I had to quit smoking, and was deep in the throes of everything mental. Called my doctor, and he prescribed Celexa...one-half pill (20 mg). I was furious! Half a pill? They either didn't have any idea what I was dealing with, or didn't care.  I griped, but I started that night, with my little `1/2 pill. The next day I didn't even think about a cigarette until I realized I hadn't thought about them! 

I love Celexa."
