the biggest mistake people make is thinking that it is going to work right away.it will actually take several weeks to get into ur system. & it will be a gradual change, not an overnight ''wow i'm better!'' feeling. as for whether or not to take it, u should listen to the advice of ur doctor.who should have done a thorough exam, talked with u in depth about ur feelings, & given u a list of side effects. if he didn't, please make sure u see him again. i think prozac helps most people, but everyone is different.so if u do not feel any different in 3 months, go back to ur doctor & talk about alternatives. also, do not suddenly stop taking it - u will need to gradually work yourself off of it, should u decide to stop. just stopping cold turkey can be dangerous. good luck.
