What Are The Side Effects Of Prozac 10?

sir , i started taking prozac 10 days ago for the first time ...for five days when i was taking 10 mg dose per day, i felt better...then i took 20 mg for the next two days as prescribed by the doctor. but there was a dramatic reversal in my mood on the seventh day as i felt extremely depressed and uncomfortable . i felt the same for around one and half days. i had take an avils pill to sleep . now on the 10th day i feel normal ( my original self ie me without meds) .
kindly advise me if i should continue the medicine.
