Maryjeandennis, It worked very well for me for 20 years then stopped working. Also I would occasionally try to get off of it but utterly impossible so I stayed on it until it stopped working. Well I couldn't even get off of it then and have stayed on it to avoid the horrendous withdrawal effects. I should say that this isn't the case for everyone. Some people have no problem getting off of it. I believe there were other factors causing my panic attacks (high heavy metals and low thyroid function) that I didn't know of at the time. I am still very grateful for Paxil; it helped greatly when I needed help.
