I got it from Holland and Barrett I think you can also get it from Amazon, you just drink I cup at night and in the morning you wake up and do a very, very big poop ! You can do it for just a week or two but no longer because I think it has laxative effects. I don't know how much weight you lose but I have used it for 2 nights in a row this time and I feel a lot less bloated so I must have lost a few inches. It's pretty cheap stuff so worth a try =) They also do a pureatee and a laxatee, my mum has got the pureatee but I havn't tried it yet and to be honest after seeing what slimatee does, I wouldn't want to try the laxatee !

EDIT -Yea I think it just helps clear you out but because it's senna I don't think it's that bad for you and I havn't had any reverse reactions =)
