i was on prozac for only a couple of weeks and i went through pure hell. I had every side effect on the list,i had to take lorezepam for the anxiety, codeine for the severe headaches it caused, i couldnt sleep, eat, walk, think, see properly, it was horrendous. i believe i dont excret drugs very well, i still have one pupil dilated now and its been nearly 2 yrs, i think my adrenals got worse than they were already. i know people on them and they are fine and working for them. i went straight in at 20mg, it was far too much for me im very small, i should have been started at 10mg or less. prozac contains fluoride, i didnt know it at the time,it wasnt the happy pill its made out to be.more like suicide pill.
