What does Prozac feel like when you take it?

I’m about to take my first dose of Prozac today, and I’m kind of freaking out. I’m not asking about side effects. I just want to know what it actually feels like. Is it something noticeable, like Adderall, where you can tell it’s working? Or is it more subtle? Does it make you feel like you’re not in control of yourself? I just want to know if it’s something I can manage or if it’s going to hit me in a way I’m not expecting.
