Is it effective??

I have been on the net in search of a medication which will help to be alcohol-free. I would like to have some feedback from people who has fought this illness which is called alcohol addiction. It seems to be very difficult to combat with alcohol but it necessary coz it can harm someone's health. I've came across a page http://www.drugdelivery.ca/s31006-s-CAMPRAL.aspx which is a medication used in the treatment of alcoholics. While reading all it's side effects, it scared me. Can anyone tell me more about campral??
