Does Prozac Cause Loss Of Memory?

Hi Doc, After an auto accident, the I was prescribed Prozac (Jan, 2014) After a few weeks, I discontinued the meds due to side effects: lack of focus, drowsy, altered heart beat, extremely slow in movement. I continued to feel terribly unorganized, I was neat and like order, everything in it's place. I have trouble remembering simple things, I write notes to remember, but forget where my notes are. I know something is truly off balance with my body, but I can't explain thoroughly. Is there anything I can do or take to reverse the possible side effects from the Prozac?
