I suffer from panic and gad. Last time I took prozac I slowly titrated up and don't remember side effects. This time I went straight onto 20mg and after 12 days I stopped it because the anxiety and panic were so unbearable. Even 5mg of diazepam didn't help and I can't take propranolol due to asthma. Has anyone had this happen to them before? Did your GP then suggest you titrate up or did they suggest a different drug?
