Have been on Celexa for 2 1/2 months now. Absolutely no side effects. I have suffered from Generalized Anxiety Disorder/ Panic Disorder for 13 years. Was taking Xanax quite often for panic attacks. In the past six weeks I have taken only two 0.25mg Xanax which is a huge improvement for me. I have lost 6 pounds and I don't have such ridiculous compulsive worries anymore. I have no sexual side effects like some people have mentioned in other posts. This medication is GREAT for me. I am so thankful I found it!
