"i been taking 200 mg for about 4 years now . but the problem is it&#039;s no longer working for me. my doctor doesn&#039;t want to give me anything that&#039;s addictive but i don&#039;t have a addictive personality over the past 4 or 5 years i have tried at least 5 different pills but none helped but hydroxyzine is good but once you get it build up in your system it no longer works . ( well at least not for me ) but everybody body&#039;s different ..... so good luck"
