Prozac

I’ve been battling depression/anxiety for a little over 6 years & I’ve finally built up the courage to go see an therapist and psychiatrist. Well I was prescribed Prozac 10mg today & I will start it tomorrow morning. My doc will up my dosage after she sees how this dose works well with me first. I’ve watched a few YouTube videos & most ppl say it has helped but, some say they suffer from vivid dreams, nightmares & weight gain. I really don’t want to gain any more so I’m praying this isn’t the case for me. Also did it effect your libido? Anyone out there on Prozac? If so, how did it work for you? I know everyone is different. Thanks
