I have been taking prozac for about 4 days now and I have really bad diarrhea and nausea! It's making my anxiety up but I do find that I can control it better than before. Also, I am really tired all of the time? I am taking 10mg prozac along with 15mg Buspar daily (I've been taking the Buspar for a while now) And I just feel like I can't get enough sleep although I sleep great throughout the night with little to no interruptions. I know I should wait it out but is there anything I could do or anyone else that has experienced this so that I can feel a little better about it?
