"i&#039;ve been on lexapro for 2 years. just recently switched to effexor and klonopin. lexapro never really did much for me. at first, after the 2-week adjustment to the medicine which was hell, i thought it worked. but it may have just been placebo more than the medicine. had multiple serious near life-changing anxiety attacks while on lexapro which is why i switched. i couldn&#039;t be happier for switching. if you have anxiety, don&#039;t waste your time with an ssri. also, i&#039;ve stopped taking lexapro multiple times. it&#039;s not too hard, you get aggravated at everything for a few days, the brain shocks aren&#039;t nearly as bad as people say they are."
