I've been toying with the idea. I was put off as I've only ever tried it once and that when I was hungover on a holiday in South East Asia. I had to run to the toilet to be sick and embarrassingly walked out halfway through. I was in a bit better shape then so that's why I attempted it. When I lose a bit more I'm going to give it another go as I've got a lot of friends who have benefited mentally and physically. Will check the link out, thanks.
