"most of my life i have struggled with severe panic attacks, general anxiety, ptsd &amp; moderate depression. been on meds twice before until i felt better &amp; then i would stop taking them. this last time it had been close to a year that i had been suffering again before i decided to reluctantly go back on meds. i tried celexa again- it worked kinda okay in the past but this time it made no improvement for me. saw the doc who switched me to prozac- all i can say is wow! best yet- i feel like my old, happy self after only 1 month! 10mg the first week, 15 the second and 20mg the last two. give it time to work &amp; be patient- it might make you feel a bit off &amp; not better at first, but it is a miracle drug. these bad feelings will pass hang in there!"
