"20 year old male.  after failing 2 of my college classes in one semester, decided it was time to do something about my increasing depression.  doctor started me on zoloft.  took about 4 weeks to start to notice the effects.  occasional shakes.  memory loss was frequent.  immediately noticed a decrease in sex drive and wasn&#039;t a problem until i started dating again and couldn&#039;t get it up the first time i got with my current girlfriend.  luckily she is understanding.  my doctor is switching me to wellbutrin.  if it wasn&#039;t for the decreased sex drive i probably would have stayed on it."
