Little turtle, I think it's not from prozac. It's more like a complete brain shutdown when I can't push myself to do anything but hide in my bed to run away from the pain. I feel completely numb and paralysed. I have experienced this a few times before I was on prozac. Moreover, I was on prozac some 25 yrs back when I was in high school and I didn't get any side-effect. But then it didn't do any wonders for me either.
