"i&#039;ve taken klonopin off and on for many years and i have to say it is very effective and much longer lasting than xanax. i&#039;ve been prescribed xanax as well and it is effective, but i truly believe it shouldn&#039;t be taken on a regular basis, especially several times a day. it&#039;s fast acting and it helps with panic attacks and similar situations. but to take it day in and day out seems ludicrous. klonopin has a much longer half life and i don&#039;t feel withdrawal when i come off klonopin, that&#039;s not the case with xanax. not only that, on xanax i was finding that i would have periods of forgetfulness, meaning periods of the day. i was at a job interview and i really couldn&#039;t tell you what was said by me or the interviewer. i did get the job however."
