Hi everyone I'm new to this and looking for some advice. I have been put on 20mg of fluoxetine due to having panic attacks and anxiety which has only happened since I lost my sister in December. I am more anxious than ever and I am now have nightmares about my sister. Could this be a possible side effect of the Prozac I have only been taking it for 12 days and have seen all the good comments on how it has helped others. I just feel that my sleeping pattern and my anxiety is terrible since starting this deug and when I do sleep which is very little I am having horrendous dreams. Can someone relate to this and will it get better or should I stop taking this medication. Thanks k x
