I have problems with major depression as well as anxiety and panic disorder. I take Effexor for the depression, and Neurontin and Klonopin for the anxiety. This worked well for a while but lately my panic attacks occassionally break through even this. My doctor suggested a small dose of Seroquel. He told me it is like a tranquilizer. Is this true and how well does this medicine work for anxiety and panic attacks? Also do most people experience weight gain? Im already on one med that made me gain 25lbs that wont budge no matter what I do. I dont want to gain anymore
