"i&#039;ve taken prozac a few times starting at 22. that 1st time was a nightmare! i literally lost time- only remember crying all the time...i don&#039;t even remember how long i took it! but that was 25 yrs ago. so i was deathly afraid to try it again til about 6 yrs ago. that time it was a lifesaver! i felt my mood lift alot after a week, then even more after a month. these results lasted for several yrs with some sexual side effects, but less than with zoloft &amp; lexapro (which also caused waking wired every 4 hrs). after a few yrs it felt like i was on nothing at all so i switched to pristiq which again, saved my life. now i&#039;m back to prozac. but i&#039;m sure it&#039;s more about what&#039;s going on in my life. nothing works without situations improving as well."
