How to search this? Just goto google and type prozac you'll get thousands of hits :)
what you'd normally expect if you just stop suddenly without consulting a doctor, is some irritability and increased deppresion, possibly higher than you ever had, but i am sure it is difirent for every person and it depends on the dosage etc , what other meds you were taking as well. carefull withdrawal might even take several weeks to finish, depends maybe on how long have you used the drug.
prozac blocks seratonin re-absorb i think in the brain, preventing levels of high deppresion to take place, but if suddenly stoped your body might go crazy, so i really suggest for you to listen carefully to your doctor he knows best, don't focus on certain symptums or try to think its better to stop the drug based on your own decision , i.e. try to play the doctor , don't do that it just makes you more confused they know more than we do :)
