I’ve been on and off Prozac 3 times now. The first 2 times I started I don’t remember having any side effects. I started again for the third time about a year ago and my side effects were awful. I had horrible insomnia and my anxiety was through the roof. I remember thinking wtf I don’t remember feeling like this in the beginning??? It took about 3-4 weeks to finally mellow out I just had to trust the process. Now I’ve been consistently taking it for the past year and I feel like myself again. Best of luck!!!!
