"i have been on lexapro for 7 months and it has helped me greatly! i was on paxil previously and gained 20kg so asked to change medication. lexapro has stopped the panic attacks and made me feel more confident, i can now go to the shops on my own, drive places on my own and hang out with friends without thinking the worse will happen. only thing is i&#039;ve gained about 8kg and i cannot lose the weight. i had no side effects what so ever when i started, maybe it&#039;s because i was previously on paxil, but i didn&#039;t have any side effects apart from weight gain with that either. so if you are feeling nervous about starting this medication because of the side effects don&#039;t be, you might be one of the lucky ones who don&#039;t get side effects."
